METHOD OF MANUFACTURING MN-ZN FERRITE CORE HAVING HIGH FREQUENCY AND LOW POWER LOSS

摘要

The present invention is Fe ₂ O ₃ and MnO as the main component on a suitable method of manufacturing the Mn-Zn based ferrite core to augment the electromagnetic characteristics by suppressing the vaporization of the metal element generated during the sintering process of the ferrite core formed article: 23~ (1, 100 to 1,450 캜) of a Mn-Zn ferrite powder obtained by mixing CaO and SiO ₂ powder or mixing 39 mol% and ZnO: 6 to 27 mol% Zn-based ferrite core characterized in that the Mn-Zn-based ferrite powder of the present invention is applied and then fired.
