Abstract:
1. A multilayer chip capacitor comprising: a capacitor body formed by laminating a plurality of dielectric layers and having top and bottom surfaces facing each other, the bottom surface to be mounted on a circuit board; a plurality of internal electrodes disposed in perpendicular to the bottom surface in the capacitor body with each of the dielectric layers interposed therebetween; a first external electrode of a first polarity formed on a first side surface of the capacitor body to partially extend to the top and bottom surfaces; a second external electrode of the first polarity formed on a second side surface opposite to the first side surface to partially extend to the top and bottom surfaces; and a third external electrode of a second polarity formed on the bottom surface between the first and second external electrodes, wherein the first and second internal electrodes are disposed in perpendicular to the bottom surface of the capacitor body, wherein each of the first internal electrodes has a first lead drawn to the first side surface and the bottom surface and a second lead drawn to the second side surface and the bottom surface, and each of the second internal electrodes has a third lead drawn to the bottom surface between the first and second leads, wherein the first lead is in contact with and fixed to the first external electrode formed on the first side surface and at least one of top and bottom surfaces, and the second lead is in contact with and fixed to the second external electrode formed on the second side surface and at least one of top and bottom surfaces, wherein the first to third leads are in contact with the first to third external electrodes through the entire length of the edge portions of the respective leads exposed to outer surfaces of the capacitor body to be connected to the first to third external electrodes, respectively, wherein a width of the third external electrode is larger than a width of a portion of the first external electrode extending to the bottom surface and a width of a portion of the second external electrode extending to the bottom surface, and wherein a width ratio of a width of the third lead to the width of the portion of the first lead drawn to the at least one of the top and bottom surfaces is 1.38 or more.
