Abstract
A MnZn-based ferrite that can reduce the loss even when a high-frequency voltage fluctuation occurs is provided. The above MnZn-based ferrite is a MnZn-based ferrite including Fe2O3, ZnO, and MnO as main components, in which of Fe2O3 is 53.2 to 56.3 mol % and ZnO is 1.0 to 9.0 mol %, with a balance of MnO, in 100 mol % of the main components, and the MnZn-based ferrite includes 0.9 to 2.0% by mass of Co2O3, 0.005 to 0.06% by mass of SiO2, and 0.01 to 0.06% by mass of CaO, as auxiliary components, per 100% by mass of the main components.
Claims5
A MnZn-based ferrite comprising Fe2O3, ZnO, and MnO as main components, wherein
