     DETAILED DESCRIPTION 
     Hereinafter, exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. 
     Directions of a hexahedron will be defined in order to clearly describe exemplary embodiments in the present disclosure. L, W and T illustrated in the drawings refer to a length direction, a width direction, and a thickness direction, respectively. Here, the thickness direction refers to a stacking direction in which dielectric layers are stacked. 
     A multilayer ceramic electronic component according to an exemplary embodiment in the present disclosure, particularly, a multilayer ceramic capacitor will hereinafter be described. However, the multilayer ceramic electronic component according to the present disclosure is not limited thereto. 
       FIG. 1  is a perspective view illustrating a multilayer ceramic electronic component included in a multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure. 
     Referring to  FIG. 1 , a multilayer ceramic electronic component  100  may include a ceramic body  110 , and first and second external electrodes  131  and  132 . 
     The ceramic body  110  maybe formed of a hexahedron having both end surfaces in a length direction L, both side surfaces in a width direction W, and both side surfaces in a thickness direction T. The ceramic body  110  may be formed by stacking a plurality of dielectric layers in the thickness direction T and then sintering the plurality of dielectric layers. A shape and a dimension of the ceramic body  1  and the number (one or more) of stacked dielectric layers are not limited to those of an example illustrated in the present exemplary embodiment. 
     The plurality of dielectric layers disposed in the ceramic body  110  may be in a sintered state, and adjacent dielectric layers may be integrated with each other so that boundaries therebetween are not readily apparent without using a scanning electron microscope (SEM). 
     For example, the ceramic body  110  may have eight rounded corners in the hexahedron. Accordingly, durability and reliability of the ceramic body  110  may be improved, and structural reliability of the first and second external electrodes  131  and  132  at the corners may be improved. 
     The dielectric layer  111  may have a thickness arbitrarily changed in accordance with a capacitance design of the multilayer ceramic electronic component  100 , and may include ceramic powders having a high dielectric constant, such as barium titanate (BaTiO 3 ) based powders or strontium titanate (SrTiO 3 ) based powders. However, a material of the dielectric layer according to the present disclosure is not limited thereto. In addition, various ceramic additives, organic solvents, plasticizers, binders, dispersants, and the like, may be added to the ceramic powders according to an object of the present disclosure. 
     An average particle size of the ceramic powders used to form the dielectric layer is not particularly limited, but may be controlled in order to accomplish an object of the present disclosure. For example, the average particle size of the ceramic powders used to form the dielectric layer may be controlled to be 400 nm or less. Accordingly, the multilayer ceramic electronic component  100  may be used as a component that greatly requires miniaturization and high capacity like an IT component. 
     For example, the dielectric layer may be formed by applying and drying a slurry including powders such as barium titanate (BaTiO 3 ) powders, or the like onto a carrier film to prepare a plurality of ceramic sheets. The ceramic sheets may be manufactured by mixing ceramic powders, a binder, and a solvent with each other to prepare a slurry and manufacturing the slurry in a sheet shape having a thickness of several micrometers by a doctor blade method, but is not limited thereto. 
     The first and second external electrodes  131  and  132  may be disposed on first and second external surfaces of the body  110  (e.g., one end surface and the other end surface of the body  110  in the length direction of the body  110 ) so as to be connected to the first and second internal electrodes, respectively, and may electrically connect between the first and second internal electrodes and the substrate. 
     For example, the first and second external electrodes  131  and  132  may be formed of copper (Cu), palladium (Pd), platinum (Pt), gold (Au), silver (Ag), lead (Pb), or the like, or alloys thereof. 
     For example, the first and second external electrodes  131  and  132  may include first and second electrode layers including copper (Cu) or nickel (Ni), and first and second plating layers disposed on the first and second electrode layers and including nickel (Ni) or tin (Sn). 
     The first and second electrode layers may be formed by a method performing a dipping in a paste including metal components, or a method of printing a conductive paste including a conductive metal on at least one surface of the ceramic body  110  in the thickness direction T of the ceramic body  110 , and may also be formed by a sheet transfer manner and a pad transfer manner. 
     The first and second plating layers may be formed according to sputtering or electric deposition, but are not limited thereto. 
       FIG. 2  is a perspective view illustrating a form of internal electrodes of the multilayer ceramic electronic component illustrated in  FIG. 1 . 
     Referring to  FIG. 2 , the ceramic body  110  may include the first and second internal electrodes  121  and  122 , and include the dielectric layer disposed between the first and second internal electrodes  121  and  122 . 
     The first and second internal electrodes  121  and  122  may be stacked to be alternatively exposed to the first and second external surfaces of the ceramic body (e.g., one end surface and the other end surface of the ceramic body in the length direction of the ceramic body) while having the dielectric layer interposed therebetween to have different polarities. 
     The first internal electrodes  121  and the second internal electrodes  122  maybe formed to be alternately exposed to one end surface and the other end surface of the ceramic body  110  in the length direction L of the ceramic body  110  in a stacking direction of the dielectric layers by printing a conductive paste including a conductive metal, and may be electrically insulated from each other by the dielectric layer disposed therebetween. 
     That is, the first and second internal electrodes  121  and  122  may be electrically connected to the first and second external electrodes  131  and  132  formed on both end surfaces of the ceramic body  110  in the length direction L of the ceramic body  110  through portions alternately exposed to both end surfaces of the ceramic body  110  in the length direction of the ceramic body  110 , respectively. 
     For example, the first and second internal electrodes  121  and  122  may be formed by the conductive paste for an internal electrode including conductive metal powders having a particle average size of 0.1 to 0.2 μm and a weight of 40 to 50 wt %. 
     The conductive paste for an internal electrode may be applied onto the ceramic sheets by a printing method, or the like, to form internal electrode patterns. A method of printing the conductive paste may be a screen printing method, a gravure printing method, or the like, but is not limited thereto. Two hundred or three hundred ceramic sheets on which the internal electrode patterns are printed may be stacked, pressed, and sintered to manufacture the ceramic body  110 . 
     Therefore, when a voltage is applied to the first and second external electrodes  131  and  132 , electrical charges may be accumulated between the first and second internal electrodes  121  and  122  facing each other. In this case, a capacitance of the multilayer ceramic electronic component  100  may be proportional to an area of a region in which the first and second internal electrodes  121  and  122  overlap each other. 
     That is, when the area of the region in which the first and second internal electrodes  121  and  122  overlap each other is significantly increased, capacitance may be significantly increased, even in a capacitor having the same size. 
     A thickness of each of the first and second internal electrodes  121  and  122  may be determined depending on the use, and may be, for example, 0.4 μm or less. In addition, the number of layers of the first and second internal electrodes  121  and  122  may be 400 or more. Accordingly, the multilayer ceramic electronic component  100  may be used as a component that greatly requires miniaturization and high capacity like an IT component. 
     Since the thickness of the dielectric layer corresponds to an interval between the first and second internal electrodes  121  and  122 , the capacitance of the multilayer ceramic electronic component  100  may be large as the thickness of the dielectric layer is shorter. 
     The conductive metal included in the conductive paste forming the first and second internal electrodes  121  and  122  may be nickel (Ni), copper (Cu), palladium (Pd), silver (Ag), lead (Pb), or platinum (Pt), or alloys thereof. However, the conductive metal according to the present disclosure is not limited thereto. 
     The withstand voltage characteristic of the ceramic body  110  may be improved as the interval between the first and second internal electrodes  121  and  122  is longer. 
     In a case in which the multilayer ceramic electronic component  100  is required to have a high withstand voltage characteristic such as electric parts, the multilayer ceramic electronic component  100  may be designed so that an average thickness of the dielectric layers exceeds twice an average thickness of the first and second internal electrodes  121  and  122 . Accordingly, the multilayer ceramic electronic component  100  may have the high withstand voltage characteristic and may be used as the electric part. 
     In addition, durability (e.g., warpage endurance) of the ceramic body  110  may have high reliability in a case in which a width of the ceramic body  110  exceeds 0.5 times the thickness thereof. 
     The capacitance of the multilayer ceramic electronic component  100  may be increased as the number of stacked layers of the first and second internal electrodes  121  and  122  and the overlap region of the first and second internal electrodes  121  and  122  are larger. The number of stacked layers of the first and second internal electrodes  121  and  122  may be increased as the thickness of the electronic component is increased, and the overlap area of the first and second internal electrodes  121  and  122  may be increased as the length and/or width of the multilayer ceramic electronic component is increased. Therefore, the capacitance of the multilayer ceramic electronic component  100  may be dependent on a size thereof. 
     However, as the size of the multilayer ceramic electronic component  100  increased, the possibility of a defect occurring in a process of manufacturing the multilayer ceramic electronic component  100  may be increased. 
     For example, as the size of the multilayer ceramic electronic component  100  is increased, the multilayer ceramic electronic component  100  may be subjected to more stress in a process of cutting the multilayer ceramic electronic component  100 , and internal burn-out may be caused according to an internal sintering imbalance when the multilayer ceramic electronic component  100  is sintered. 
       FIG. 3A  is a perspective view illustrating a multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure. 
     Referring to  FIG. 3A , a multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may include a plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c , and an interposer  200   a.    
     That is, one multilayer ceramic electronic component may be divided into the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c . Accordingly, the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may reduce a defect in a process of manufacturing thereof while having a high capacitance. 
     The plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  may be designed in the same manner as the multilayer ceramic electronic component illustrated in  FIGS. 1 and 2 . 
     The interposer  200   a  may provide an arrangement space of the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c , and include an insulating body  210 , and first and second terminal electrodes  221  and  222 . 
     In addition, the interposer  200   a  may attenuate acoustic noise while suppressing a transmission of the acoustic noise that may occur in the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  to the substrate below the interposer  200   a . Accordingly, the acoustic noise may be reduced. 
     For example, the insulating body  210  maybe implemented of the same material as that of an insulating layer of a printed circuit board (PCB), and may be implemented with high Young&#39;s modulus such as alumina to efficiently reduce the acoustic noise of the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c.    
     The first and second terminal electrodes  221  and  222  may electrically connect between the substrate below thereof and the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c . That is, the first and second terminal electrodes  221  and  222  may be electrically connected to the first and second external electrodes  131  and  132 , respectively. 
       FIG. 3B  is a perspective view illustrating a form in which a recessed region is added in the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure. 
     Referring to  FIG. 3B , the interposer  200   b  may include first recessed regions and second recessed regions  232  positioned on an end surface of the insulating body  210  in a length direction thereof. That is, the first and second terminal electrodes  221  and  222  may include the first recessed regions and the second recessed regions  232 , respectively. 
     The first recessed regions and the second recessed regions may be spaces in which at least a portion of the solder may be disposed when the multilayer ceramic electronic component array is mounted on the substrate. A ratio of a portion of the solder that rises to the side surfaces of the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  may be decreased as at least a portion of the solder is positioned in the first recessed regions and the second depression regions  232 , Since the portion of the solder positioned on the side surfaces of the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  may act as a path of acoustic noise, the acoustic noise of the multilayer ceramic electronic component array may be more efficiently reduced as the ratio of the portion of the solder rising to the side surfaces of the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  is lower. 
     Meanwhile, the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may efficiently reduce the acoustic noise by using at least one of linkage structures between the plurality of multilayer ceramic electronic components  100   a ,  100   b , and  100   c  illustrated in  FIGS. 4A through 4C . 
       FIG. 4A  is a perspective view illustrating an external electrode linkage of the multilayer ceramic electronic component. 
     Referring to  FIG. 4A , the respective first external electrodes  131  of the plurality of multilayer ceramic electronic components may be in contact with each other, and the respective second external electrodes  132  of the plurality of multilayer ceramic electronic components may be in contact with each other. 
     Accordingly, at least portions of the respective acoustic noises of the plurality of multilayer ceramic electronic components may be offset with each other, and fixing strength may be improved when the plurality of multilayer ceramic electronic components are mounted. 
     Table 1 below illustrates acoustic noise according to whether or not the first and second external electrodes  131  and  132  are in contact with each other. Here, a thickness of the interposer may be 0.2 mm, one multilayer ceramic electronic component may have a size of 1005, a capacitance of one multilayer ceramic electronic component may be 47 μF, and the internal electrodes and the interposer may be disposed to be perpendicular to each other.

     Table 2 below illustrates fixing strength when the multilayer ceramic electronic components are mounted according to whether or not the first and second external electrodes  131  and  132  are in contact with each other. Here, the fixing strength refers to a reference force at which the multilayer ceramic electronic component is separated when a lateral force is applied to the multilayer ceramic electronic component. Experimental conditions are the same as in Table 1.

     Referring to Table 2, the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may have a structure in which the plurality of multilayer ceramic electronic components on the interposer are connected to each other through the contact of the first and second external electrodes, thereby improving the fixing strength. 
       FIG. 4B  is a perspective view illustrating an insulating member linkage of the multilayer ceramic electronic component. 
     Referring to  FIG. 4B , the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may further include an insulating member  150  which is contact with the ceramic body  110  of each of the plurality of multilayer ceramic electronic components and is more flexible than the ceramic body  110  and/or the dielectric layer. 
     Accordingly, the respective acoustic noises of the plurality of multilayer ceramic electronic components may be more efficiently offset. 
     For example, the insulating member  150  may include an epoxy to more efficiently offset the respective acoustic noises of the plurality of multilayer ceramic electronic components, but is not limited thereto. 
     Table 3 below illustrates the acoustic noise according to the presence or absence of the insulating member  150 . Here, the insulating member  150  may be an epoxy, and the first and second external electrodes  131  and  132  may be bonded to each other. The remaining experimental conditions are the same as in Table 1.

     Referring to Table 4, the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may include the insulating member  150 , thereby further improving the fixing strength. 
       FIG. 4C  is a perspective view illustrating a solder linkage of the multilayer ceramic electronic component. 
     Referring to  FIG. 4C , the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure may further include a first solder and a second solder  240 . 
     The first solder may be in contact with the first terminal electrode, and at least a portion thereof may be positioned between the respective first external electrodes  131  of the plurality of multilayer ceramic electronic components. 
     The second solder  240  may be in contact with the second terminal electrode, and at least a portion thereof may be positioned between the respective second external electrodes  132  of the plurality of multilayer ceramic electronic components. 
     Here, the insulating member illustrated in  FIG. 4B  may be disposed to be in contact with the first solder and the second solder  240 . 
     Accordingly, since the insulating member  150  may be linkaged with the first solder and the second solder  240 , the insulating member  150  may more efficiently reduce the acoustic noise. 
       FIGS. 5A and 5B  are side views illustrating a parallel structure of internal electrodes of the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure. 
     Referring to  FIGS. 5A and 5B , the respective first internal electrodes  121  of the plurality of multilayer ceramic electronic components may be disposed to be in parallel to each other, and the respective second internal electrodes  122  of the plurality of multilayer ceramic electronic components may be disposed to be in parallel to each other. 
     As shown in  FIG. 5A , the first second internal electrodes  121  and  122  may be disposed to be parallel to a mounting surface of the interposer  200   b.    
     As shown in  FIG. 5B , the first and second internal electrodes  121  and  122  may be disposed to be perpendicular to a mounting surface of the interposer  200   b.    
     Accordingly, since the respective acoustic noises AN may have displacements opposite to each other, the acoustic noises may be efficiently offset with each other. 
       FIGS. 6A through 6D  are perspective views illustrating various forms of an interposer included in the multilayer ceramic electronic component array according to an exemplary embodiment in the present disclosure. 
     Referring to  FIG. 6A , an interposer  200   a  may have neither a recessed region nor a groove. 
     Referring to  FIG. 6B , an interposer  200   b  may have only first and second recessed regions  231  and  232  among the first and second recessed regions  231  and  232  and the groove. 
     Referring to  FIG. 6C , an interposer  200   c  may have only first and second grooves  241  and  242  among the recessed region and the first and second grooves  241  and  242 . 
     Referring to  FIG. 6D , an interposer  200   d  may have both the first and second recessed regions  231  and  232  and the first and second grooves  241  and  242 . 
     The first and second grooves  241  and  242  may be positioned between the plurality of multilayer ceramic electronic components on an upper surface of the insulating body  210 . 
     Accordingly, since a portion of the solder may be filled in the first and second grooves  241  and  242 , the ratio of the portion of the solder rising up to the side surfaces of the plurality of multilayer ceramic electronic components may be reduced. Therefore, the acoustic noise may be further reduced. 
     In addition, a contact area between the solder and the insulating member may be increased as a portion of the solder is filled in the first and second grooves  241  and  242 . Therefore, the acoustic noise may be more efficiently offset. 
     As set forth above, according to the exemplary embodiment in the present disclosure, the multilayer ceramic electronic component array may secure large capacitance, reduce the acoustic noise, and have strong fixing strength for the substrate. 
     While exemplary embodiments have been shown and described above, it will be apparent to those skilled in the art that modifications and variations could be made without departing from the scope of the present invention as defined by the appended claims.
