  • ESD protective device and method for manufacturing thereof
    Patent number: 10297982
    Abstract: An ESD protective device includes an element assembly with a hollow portion that includes inner surfaces including a first inner surface, a second inner surface, and a third inner surface inclined to a Z direction in a cross section including the Z direction. Accordingly, a surface area of the inner surfaces of the hollow portion is increased, the heat load on an auxiliary discharge electrode is reduced, and the deterioration of the auxiliary discharge electrode is significantly reduced or prevented.
    Type: Grant
    Filed: February 6, 2017
    Date of Patent: May 21, 2019
    Assignee: MURATA MANUFACTURING CO., LTD.
    Inventors: Yoshihito Okutomi, Jun Adachi
  • Ceramic electronic component
    Patent number: 9959975
    Abstract: A ceramic electronic component that includes a ceramic element, and a coating film and external electrodes on a surface of the ceramic element. The coating film includes cationic elements from a constituent element of the ceramic element, which are ionized and deposited from the ceramic element, and a resin. The surface of the coating film is recessed relative to a surface of wrapping parts of the external electrodes on the surface of the ceramic element.
