  • Publication number: 20180068796
    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.

  • Publication number: 20180035545
    Abstract: A multilayer capacitor includes a capacitor body including dielectric layers and a plurality of first and second internal electrodes alternately disposed with one of the dielectric layers interposed between each pair of adjacent first and second internal electrodes. First and second via electrodes penetrate through the plurality of second internal electrodes to thereby be exposed to a first surface of the capacitor body, and are disposed to be spaced apart from each other. First and second external electrodes are disposed on two side surfaces of the capacitor body and connected to opposing ends of the first internal electrodes, respectively. Third and fourth external electrodes are disposed on the first surface of the capacitor body to be spaced apart from each other, and are connected to end portions of the first and second via electrodes, respectively.
