POWDER FOR MAGNETIC FERRITE, MAGNETIC FERRITE MULTILAYER FERRITE COMPONENTS AND PRODUCTION METHOD THEREOF

摘要

Characterized in that the present invention is that comprising a Fe ₂ O ₃ 40~51% mol, CuO 7~30 mol%, ZnO 0.5~35 mol% MgO and 5~35 mol%, the particle size distribution peaks located at 0.3~1.2 ㎛ It relates to a multi-layer ferrite parts produced using the powder for a magnetic ferrite of. The MgCuZn ferrite has the particle size distribution peak is located in the 0.3~1.2 ㎛, the deterioration of the magnetic permeability (μ) write down it can be co-fired with the Ag or Ag alloy. Further, to provide magnetic properties, in particular, less deterioration of the magnetic permeability (μ) to stress, low-temperature co-fired temperature, that is, Ag or magnetic ferrite, which can be fired at a temperature below the melting point of the Ag alloy used as the electrode material.
