  • Patent number: 11443895
    Abstract: A multilayer ceramic capacitor includes a laminate including a dielectric ceramic layer and first and second electrode layers laminated in a lamination direction, and first and second external electrodes respectively connected to the first and second internal electrode layers. The laminate includes a central layer portion, a peripheral layer portion sandwiching the central layer portion, and a side margin sandwiching the central layer portion and the peripheral layer portion. The first and second internal electrode layers and the first and second external electrodes include Ni. In a cross section including the lamination direction and a width direction, a Ni content of the peripheral layer portion is larger at a surface portion than at a central portion in a thickness direction, and a Ni content of the side margin is larger at a surface portion than at a central portion in a thickness direction of the side margin.

  • Publication number: 20220262568
    Abstract: A multilayer ceramic capacitor includes first dielectric ceramic layers each with a thickness of about 0.48 ?m or more and about 0.50 ?m or less in the lamination direction, and additional dielectric ceramic layers each with a thickness of about 10 ?m or more and about 15 ?m or less in the width direction. A number of dielectric particles in each first dielectric ceramic layer in a thickness direction is three or more and six or less. A number of dielectric particles in each additional dielectric ceramic layer in a thickness direction is 100 or more and 150 or less. When the number of dielectric particles in each of first dielectric ceramic layer is NT, and the number of dielectric particles in each additional dielectric ceramic layer is NW, a ratio of NT to NW is about 1:23.08 or more and about 1:46.15 or less.
