  • Patent number: 6817085
    Abstract: A method of manufacturing a multi-layer ferrite chip inductor array including an element main body composed by laminating a ferrite layer and a conductor layer in such a manner that the laminated face thereof is vertical with an element mounting surface. The method also includes furnishing a plurality of coil shaped internal conductors within the element main body, in which a coiling direction of the coil shaped internal conductor is in parallel with the element mounting surface, forming the ferrite sheets with through-holes and printing the ferrite sheets with a plurality of coil shaped internal conductors and conductor patterns with an electrically conductive material.
    Type: Grant

    Inventors: Fumio Uchikoba, Tomoyuki Tatemori
  • Patent number: 6489875
    Abstract: A multi-layer ferrite chip inductor array, wherein an element main body 11 is composed by laminating a ferrite layer and a conductor layer in such a manner that the laminated face thereof is vertical with an element mounting surface 15, a plurality of coil shaped internal conductors are furnished within the element main body 11, the coiling direction of said coil shaped internal conductor being parallel with the element mounting surface, and the ferrite sheets formed with through-holes are printed with a plurality of coil shaped internal conductors and conductor patterns with the electrically conductive material, and the ferrite sheets are laminated such that the laminated face thereof is vertical with the element mounting surface. This realization of the invention depends on the production method having the process enabling to obtain the laminated body where the plurality of coil shaped internal conductors are formed, the coiling direction of said conductors being parallel with said element mounting surface.
