  • Patent number: 11848161
    Abstract: Provided are a multilayer ceramic capacitor and a board having the same, the multilayer ceramic capacitor including: a capacitor body including an active region, which includes a plurality of dielectric layers and a plurality of internal electrodes alternately disposed with respective dielectric layers interposed therebetween, and covers formed on and under the active region, respectively. The multilayer ceramic capacitor further includes external electrodes disposed on the capacitor body so as to be connected to the internal electrodes. Among the internal electrodes, an internal electrode disposed adjacently to one of the covers has at least one cutaway portion within a portion of the internal electrode connected to the external electrode, and the cutaway portion is (at least partially) filled with a dielectric material.
    Type: Grant

  • Patent number: 11742147
    Abstract: The multilayer ceramic electronic component includes a ceramic body including a dielectric layer; and first and second internal electrodes disposed inside the ceramic body, and disposed to oppose each other with the dielectric layer interposed therebetween. When an average thickness of the dielectric layer is referred to as td and a standard deviation of a thickness of the dielectric layer in each position is referred to as ?td, while an average thickness of the first and second internal electrodes is referred to as te and a standard deviation of a thickness of a pre-determined region of any layer of the internal electrodes in each position is referred to as ?te, a ratio (?te/?td) of the standard deviation of the internal electrodes in each position to the standard deviation of the thickness of the dielectric layer in each position satisfies 1.10??te/?td?1.35.
