  • Multilayer ceramic capacitor and board having the same
    Patent number: 10770233
    Abstract: A multilayer ceramic capacitor includes a ceramic body including an active portion including dielectric layers and internal electrodes that are alternately stacked and a margin portion disposed on outer surfaces of the active portion; and external electrodes disposed on outer surfaces of the ceramic body. The margin portion includes an inner half adjacent to the active portion and an outer half adjacent to the edge of the ceramic body, and a porosity of the inner half is greater than a porosity of the outer half.
    Type: Grant
    Filed: June 18, 2019
    Date of Patent: September 8, 2020
    Assignee: SAMSUNG ELECTRO-MECHANICS CO., LTD.
