The ferrite material of the present invention is 0.05 to 1.0% by weight of bismuth oxide in terms of Bi 2 O 3 , 0.5 to 3.0% by weight of tin oxide in terms of SnO 2 , and Cr 2 O 3 with respect to a predetermined main component mixture composition. Since it is configured to add 30 to 5000 ppm by weight in terms of conversion, it is possible to improve the DC overlapping characteristic, the temperature characteristic of the initial permeability, the improvement of the specific resistance, and at the same time, Improvement can be aimed at.n n n Ferrite, Bismuth Oxide, Tin Oxide, Chromium Oxide, Permeability, Core |
