Patent ID: 8563871

Claim:
A composite electronic part comprising magnetic and dielectric materials, the part being made by co-sintering at a temperature of 1000° C. or lower, wherein the magnetic material comprises a ferrite comprising 46 to 48 mol % of Fe 2 O 3 , 15 to 36 mol % of ZnO, 10 to 14 mol % of CuO and the balance being NiO; wherein the dielectric material has a dielectric constant of 1000 or higher; and wherein the dielectric material comprises a barium titanate based dielectric material to which 0.5 weight parts or more and 4.0 weight parts or less of CuO and 4.0 weight parts or more and 9.0 weight parts or less of Bi 2 O 3 are added with respect to 100 weight parts of the barium titanate based dielectric material.
