摘要： A capacitor component includes a body having a stacked portion in which first internal electrodes and second internal electrodes are alternately stacked with each other and with dielectric layers therebetween in a first direction, and having first and second connection portions disposed on opposite surfaces of the stacked portion, respectively, in a second direction perpendicular to the first direction. First and second external electrodes are disposed on the first and second connection portions, respectively. The first and second connection portions each include a metal layer disposed on the stacked portion and a ceramic layer disposed on the metal layer. Corners of the body have a rounded shape in a cross-section of the body extending in the first and second directions.

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.
