摘要: A ferrite material of the present invention is configured such that 0.05 to 1.0 wt % of bismuth oxide in terms of Bi2O3, 0.5 to 3.0 wt % of tin oxide in terms of SnO2, and 30 to 5000 wt ppm of chromium oxide in terms of Cr2O3 are added to a predetermined main component mixture composition. Therefore, it is possible to achieve an improvement in DC bias characteristics, an improvement in temperature characteristics of initial magnetic permeability, and an improvement in resistivity and further achieve an improvement in burned body strength, particularly in burned body flexural strength (bending strength).

摘要: There can be provided an NiCuZn-based ferrite material containing an iron oxide, a copper oxide, zinc oxide and a nickel oxide in predetermined amounts as main components and a bismuth oxide, a silicon oxide, magnesium oxide and a cobalt oxide in predetermined amounts as additional components. Due to the predetermined amounts of the additional components, the ferrite material has an extremely good temperature characteristic (a change in permeability along with a change in temperature is small), a high quality coefficient Q and high strength.
