PURPOSE: To obtain an Mn-Zn ferrite which is less in loss in a wide magnetic flux density range in a frequency domain of over 200kHz. CONSTITUTION: Si, Ca, Ta, and Zr oxides are mixed with a basic component composed of 50-60mol% Fe2 O3 , <=15mol% ZnO, and 25-50mol% MnO at ratios of 0.005-0.1wt.%, 0.01-0.3wt.%, 0.01-0.1wt.%, and 0.01-0.15wt.% expressed in terms of SiO2 , CaO, Ta2 O5 , and ZrO2 , respectively. |
