Abstract

A multilayer capacitor includes a body including a stacked structure having dielectric layers, and internal electrodes, and external electrodes. The body has a central portion, and cover portions disposed above and below the central portion, the body has a first surface and a second surface to which the internal electrodes are exposed and which oppose each other, a third surface and a fourth surface which oppose each other in the stacking direction of the dielectric layers, and a fifth surface and a sixth surface which are connected to the first to fourth surfaces and oppose each other, and a surface roughness of each of the third to sixth surfaces of the body is greater than a surface roughness of each of the first and second surfaces of the body.

Dependent claims

A multilayer capacitor comprising:

a body including a stacked structure having a plurality of dielectric layers, and a plurality of internal electrodes stacked with the plurality of dielectric layers interposed therebetween;
and
external electrodes disposed on external surfaces of the body and electrically connected to the plurality of internal electrodes,
wherein the body has a central portion, and cover portions disposed above and below the central portion in a stacking direction of the plurality of dielectric layers,
the body has a first surface and a second surface from which the plurality of internal electrodes are exposed and which oppose each other, a third surface and a fourth surface which oppose each other in the stacking direction of the plurality of dielectric layers, and a fifth surface and a sixth surface which are connected to the first to fourth surfaces and oppose each other, and
a surface roughness of each of the third to sixth surfaces of the body is greater than a surface roughness of each of the first and second surfaces of the body.

A multilayer capacitor comprising:

a body including:
a stacked structure having dielectric layers, and first and second internal electrodes stacked with the dielectric layers interposed therebetween and respectively exposed from end surfaces of the body, and
a margin covering the stacked structure except the end surfaces;
and
first and second external electrodes disposed on the end surfaces of the body and electrically connected to the first and second internal electrodes, respectively,
wherein a surface roughness of the margin is greater than a surface roughness of each of the end surfaces, and
opposing ends of each of the first and second internal electrodes, in a width direction of the body, are in contact with the margin.
