Abstract: A multilayer capacitor includes a capacitor body including dielectric layers and first and second internal electrodes, the capacitor body having first to sixth surfaces, the first internal electrode being exposed through the third, fifth, and sixth surfaces, and the second internal electrode being exposed through the fourth, fifth, and sixth surfaces, a first side portion and a second side portion, respectively disposed on the fifth surface and the sixth surface of the capacitor body, and a first external electrode and a second external electrode, respectively be connected to the first internal electrode and the second internal electrode. The first and second side portions comprise an acicular second phase including a glass comprising aluminum (Al) and silicon (Si), manganese (Mn), and phosphorus (P), and a volume of the second phase is 30% or more with respect to the entire first and second side portions.

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.
