  • Multilayer capacitor including internal electrodes having pores on ends thereof and board having the same mounted thereon
    Patent number: 11961681
    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.
    Type: Grant
