Abstract: A multilayer capacitor includes a capacitor body including a plurality of first and second internal electrodes alternately stacked with dielectric layers interposed therebetween. A first via electrode penetrates through the plurality of first internal electrodes and is exposed at the first surface of the capacitor body. A second via electrode penetrates through the plurality of second internal electrodes, is exposed at the first surface of the capacitor body, and is spaced apart from the first via electrode. First and second external electrodes are on a first surface of the capacitor body, spaced apart from each other, and respectively connected to end portions of the first and second via electrodes. The first and second external electrodes each include a nickel (Ni) layer on the first surface of the capacitor body and a gold (Au) plating layer on the nickel layer.

Abstract: A capacitor includes a body including a plurality of dielectric layers, first and second internal electrodes alternately disposed with respective dielectric layers interposed therebetween, and first and second insulating regions. The first insulating region is disposed in each of the first internal electrodes and includes a first connection electrode disposed therein. The second insulating region is disposed in each of the second internal electrodes and includes a second connection electrode disposed therein. The products D1×Td and D2×Td are greater than 20 μm2, where Td is a thickness of the dielectric layer, and D1 and D2 are widths of the first and second insulating regions, respectively.
