Abstract: A multilayer capacitor includes a body including a dielectric layer and a plurality of internal electrodes stacked on one another with the dielectric layer interposed therebetween, and external electrodes disposed externally on the body, and each connected to the plurality of internal electrodes, wherein at least one of the plurality of internal electrodes includes an alloy region formed in a region in contact with a corresponding external electrode of the external electrodes, and the alloy region includes a nickel (Ni)-chromium (Cr) alloy.

Abstract: A multilayer ceramic capacitor include: a ceramic body including first and second surfaces opposing each other and third and fourth surfaces connecting the first and second surfaces; a plurality of internal electrodes disposed inside the ceramic body and exposed to the first and second surfaces, the plurality internal electrodes each having one end exposed to the third or fourth surface; and first and second side margin portions disposed on sides of the internal electrodes exposed to the first and second surfaces. A dielectric composition of the first and second side margin portions is different from a dielectric composition of the ceramic body, and a dielectric constant of the first and second side margin portions is lower than a dielectric constant of the ceramic body.

Abstract: A multilayer capacitor includes a capacitor body including dielectric layers and internal electrodes alternately disposed with the dielectric layers interposed therebetween; and an external electrode disposed on the capacitor body to be connected to one or more of the internal electrodes. Porosity of ends of the internal electrodes is less than 50% on an interfacial surface between a margin of the capacitor body in a width direction the capacitor body and the internal electrodes.
