摘要： A multilayer ceramic capacitor includes a ceramic body having a dielectric layer, a plurality of internal electrodes disposed in the ceramic body, and a first side margin portion and a second side margin portion arranged on end portions of the internal electrodes exposed through respective opposing surfaces of the ceramic body. The ceramic body includes an active portion having the plurality of internal electrodes arranged to overlap each other with the dielectric layer interposed therebetween to form capacitance, and cover portions disposed above an uppermost and below a lowermost internal electrode of the active portion. The first and second side margin portions include tin (Sn), and a content of Sn included in the first and second side margin portions is greater than a content of Sn included in the dielectric layer of the active portion.

摘要： A multilayer capacitor includes a body including dielectric layers and internal electrodes, and external electrodes, wherein the body has first and second surfaces opposing each other in a first direction, third and fourth surfaces opposing each other in a second direction, and fifth and sixth surfaces opposing each other in a third direction perpendicular to the first and second directions. A length of a portion of the plurality of internal electrodes in the third direction in an intermediate region of the body in the first direction is greater than a length of the first surface or the second surface of the body in the third direction. The plurality of internal electrodes have a bottleneck structure between the intermediate region and at least one of the first and second surfaces, and wherein the bottleneck structure has a shape recessed into an inner portion of the body.
