ABSTRACT:
A ferrite substrate for thin-film inductors is provided by means of blending raw materials to meet a composition of di-iron trioxide (Fe2O3): 40 to 55 mol %, nickel oxide (NiO): 5 to 35 mol %, zinc oxide (ZnO): 10 to 40 mol %, and bismuth trioxide (Bi2O3): 150 to 750 ppm, or of Fe2O3: 40 to 55 mol %, NiO: 5 to 35 mol %, ZnO: 10 to 40 mol %, cupric oxide (CuO): 5 to 10 mol %, and manganese dioxide (MnO2): 0.5 to 2 mol %, and then molding and sintering the blended material, and applying hot isostatic pressing to the sintered article. A thin-film common mode filter and a thin-film common mode filter array using the ferrite substrate and the manufacturing method of the substrate are also provided.
