Multilayered Chip-Type Power Inductor and Manufacturing Method Thereof

摘要

invention stacked chip type inductor and a method of manufacturing the power is on. The present invention is Mn-Zn-based or Mn-Mg-Zn ferrite and ferrite-based magnetic material layer is formed of a, is formed of copper, the inner electrode is formed into a coil shape on the inside of the ferrite magnetic material layer and on both sides or upper and lower surfaces of the ferrite magnetic material layer formed, the stacked chip type power inductor comprising an internal electrode and an external electrode that is electrically connected with both sides exposed or upper and lower surfaces of the ferrite magnetic layers is disclosed. The present invention also Mn-Zn-based or Mn-Mg-Zn-based ferrite powder as a molding substrate and the green laminate and the copper is green laminated body formation step of laminating the green shaped article comprising an inner electrode is printed on the surface to be formed the body including the external electrode forming step of forming external electrodes, each connected to the internal electrodes are exposed to both side surfaces or upper and lower surfaces of the green laminated body, and sintering the sintered laminate to form the sintered laminated body was sintered in a reducing atmosphere discloses a multilayered chip-type power inductor made of the manufacturing method. ;
