The present invention relates to a multilayer ceramic electronic component that can improve the short circuit failure between internal electrodes and reduce acoustic noise generated by the multilayer ceramic electronic component when a voltage is applied.
Electronic parts using ceramic materials include capacitors, inductors, piezoelectric elements, varistors, or thermistors.
Among such ceramic electronic components, a multilayer ceramic capacitor (MLCC) is advantageous in that it is small in size, but has a high capacity and is easy to mount.
The multilayer ceramic capacitor is mounted on a circuit board of various electronic products such as a computer, a personal digital assistant (PDA) or a mobile phone, and plays an important role in charging or discharging electricity. It has various sizes and lamination forms depending on the application and capacity used.
In particular, with recent miniaturization of electronic products, multilayer ceramic capacitors used in the electronic products are also required to be ultra-miniaturized and ultra-high capacity.
Therefore, a multilayer ceramic capacitor is manufactured in which a dielectric layer and internal electrodes are thinned for ultra-miniaturization of a product, and a large number of dielectric layers are laminated for ultra-high capacity.
Among them, there is a multilayer ceramic capacitor in which all external electrodes are located on the lower surface. The multilayer ceramic capacitor having such a structure has advantages such as excellent mounting density and capacity and low ESL, but it is cut when the ceramic body is cut. There is a disadvantage in that a short circuit failure between internal electrodes due to a positional shift phenomenon of opposing internal electrodes due to stress is likely to occur.

The first internal electrode 121 is formed to be exposed to the first and second end faces 3 and 4, and the second internal electrode 122 is formed to be spaced apart from the first and second end faces 3 and 4 by a certain distance. Therefore, it is possible to improve the short-circuit failure between the internal electrodes due to the displacement phenomenon of the opposing internal electrodes due to the cutting stress when the ceramic body is cut.
Specifically, the first internal electrode 121 formed to be exposed to the first and second end faces 3 and 4 and the first inner electrode 121 formed to be spaced apart from the first and second end faces 3 and 4 by a certain distance. Since the two internal electrodes 122 are alternately stacked, it is possible to improve short-circuit defects between the internal electrodes.

The heights of the insulating layer and the external electrode can be measured with reference to the mounting surface, that is, the first side surface.
According to the present embodiment, since the height of the insulating layer 141 formed on the first side surface 1 is lower than the height of the first and second external electrodes 131 and 132, the multilayer ceramic capacitor 100 is more stably on the circuit board. Can be implemented.

The insulating layers 141, 143, and 144 are not particularly limited, and may include, for example, one or more selected from the group consisting of epoxy, heat resistant polymer, glass, and ceramic.
According to an embodiment of the present invention, the insulating layers 141, 143, and 144 may be formed of a ceramic slurry.
The formation position and height of the insulating layers 141, 143, and 144 can be adjusted by adjusting the amount and shape of the ceramic slurry.

Insulating layers 141, 143, and 144 formed on the first side surface, the first end surface, and the second end surfaces 1, 3, and 4, and the second internal electrode 122 is connected to the first and second end surfaces 3 and 4, respectively. The separated length can be 1-150 μm.
The insulating layer may be formed to cover all the exposed portions of the superimposed first and second internal electrodes.
The description will focus on components that are different from the above-described embodiment of the present invention, and detailed descriptions of the same components will be omitted.
The multilayer ceramic capacitor 100 according to an embodiment of the present invention may have a length in which the second internal electrode 122 is separated from the first and second end surfaces 3 and 4 to 1 to 150 μm.
As described above, the length of the second internal electrode 122 spaced apart from the first and second end faces 3 and 4 is adjusted to be 1 to 150 μm so as to be opposed by cutting stress when the ceramic body is cut. It is possible to improve the short-circuit failure between the internal electrodes due to the positional deviation phenomenon of the internal electrodes.
Specifically, the first internal electrode 121 is formed to be exposed to the first and second end faces 3 and 4, and the second internal electrode 122 is spaced from the first and second end faces 3 and 4 at a constant interval. Since they are formed apart from each other, it is possible to improve the short-circuit failure between the internal electrodes due to the positional deviation phenomenon of the opposing internal electrodes due to the cutting stress when the ceramic body is cut.

If the distance between the second internal electrode 122 and the first and second end faces 3 and 4 is less than 1 μm, the distance between the second internal electrode 122 and the first end surfaces 3 and 4 may be short.
If the length of the second internal electrode 122 separated from the first and second end faces 3 and 4 exceeds 150 μm, the overlapping area between the first internal electrode and the second internal electrode is small, so that the capacitance increases. There is no effect.
Table 1 shows a multilayer ceramic capacitor according to an embodiment of the present invention, wherein the length L between the first and second end faces 3 and 4 and the second internal electrode 122 are the first and second end faces 3 and 4. 4 compares the relative capacitance, the short-circuit occurrence rate, and the moisture resistance load failure rate due to the lengths Lm1 and Lm2 separated from 4.
The relative capacitance is a percentage of the capacitance of the multilayer ceramic capacitor according to the present invention as compared with the capacitance of a general multilayer ceramic capacitor.
The electrostatic capacity and the short-circuit occurrence rate were determined by measuring the electrostatic capacity after applying a voltage of 4 V to the sample, and determining that a short circuit occurred when short-circuited and energized.
The humidity resistance failure rate was 80 ° C. and a relative humidity of 80%. The insulation resistance was measured for 24 hours, and when a short circuit occurred, it was judged as defective.
The sample was selected based on a model of 0603 size (0.6 mm × 0.3 mm × 0.3 mm) having a capacitance of 2.2 μF.
Referring to Table 1 above, it can be seen that the multilayer ceramic capacitor according to an embodiment of the present invention increases the short-circuit occurrence rate and the moisture load failure rate when it is out of the numerical range of the present invention.
On the other hand, when the numerical range of the present invention is satisfied, it can be seen that the occurrence rate of short circuit and the defective load resistance against moisture load decrease.
Table 2 shows the relative capacitance and the short-circuit occurrence rate according to the length of the second internal electrode 122 separated from the first and second end faces 3 and 4 in the multilayer ceramic capacitor according to another embodiment of the present invention. In addition, the moisture load failure rate is compared.
The sample was selected based on a product of a model having a length × width × height of 2.0 mm × 1.25 mm × 1.25 mm and a capacitance of 2.2 μF.
Referring to Table 2 above, it can be seen that the multilayer ceramic capacitor according to another embodiment of the present invention has a decrease in relative capacitance or a short-circuit occurrence rate and a moisture-proof load failure rate when out of the numerical range of the present invention. .
On the other hand, when the numerical range of the present invention is satisfied, the capacitance increases, and it is understood that the short-circuit occurrence rate and the moisture load resistance rate decrease.
According to an exemplary embodiment of the present invention, the first and second internal electrodes may have overlapping regions formed at portions exposed on the first side surface, and the capacitance of the multilayer ceramic capacitor may be increased.
Moreover, the short defect between internal electrodes can be improved by exposing the 1st and 2nd internal electrode to one side surface of a ceramic main body alternately.
