Abstract: A multilayer capacitor includes a body including dielectric layers and internal electrodes and external electrodes disposed on an external surface of the body and connected to the internal electrodes. The body includes a first surface and a second surface to which the internal electrodes are exposed, the first surface and the second surface opposing each other in a first direction, a third surface and a fourth surface opposing each other in a second direction which is a direction in which the dielectric layers are stacked, and a fifth surface and a sixth surface opposing each other in a third direction. At least one of the internal electrodes include a first bottleneck structure having a first directional length of a third-directional outer region smaller than an inner region thereof and a second bottleneck structure having a third directional length of a first directional outer region smaller than an inner region thereof.

Abstract: 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.
