PURPOSE: To obtain a ferrite sintered compact ensuring a small loss (core loss) and usable for the transformer of a switching power source, etc., with Ni-Cu-Zn ferrite having high specific resistance. CONSTITUTION: This Ni-Cu-Zn ferrite sintered compact satisfies X/Y<=3.0 (X is the amt. of Cu at grain boundaries in a section of this sintered compact and Y is the amt. of Cu in grains in the section) and ensures <=30kW/m<3> (50kHz, 50mT) min. value of loss (core loss) at 20-140 deg.C. |
