PURPOSE:To reduce the core loss and increase the resistivity by specifying the P content of a sintered compact contg. Fe2O3, NiO and ZnO. CONSTITUTION:A mixture of 40-52.5mol% Fe2O3 having <=10ppm P content with 5-47.5mol% NiO, <=35mol% ZnO and CuO is temporarily burnt and crushed to obtain burnt powder. This powder is blended with a binder, granulated, compacted into a ring-shaped core and burnt to obtain the objective Ni-contg. low loss ferrite for a power source having <=66ppm P content. |
