Nizn ferrite, and magnetic core and noise filter using same
Provided are: a NiZn ferrite which has excellent productivity and is capable of suppressing an increase in the rate of change in complex relative permeability with respect to temperature; and a noise filter which uses the NiZn ferrite. The NiZn ferrite is composed of Fe in an amount of 47.50 mol% or more and 48.60 mol% or less in terms of Fe2O3, Zn in an amount of 29.00 mol% or more and 30.10 mol% or less in terms of ZnO, Cu in an amount of 5.50 mol% or more and 6.50 mol% or less in terms of CuO, and Ni in an amount of 14.80 mol% or more and 18.00 mol% or less in terms of NiO, the total amount of Fe2O3, ZnO, NiO and CuO being 100 mol%, and the total amount of Fe2O3 and ZnO being 77.00 mol% or more and 78.50 mol% or less.
本发明提供一种生产性优异、且能够抑制复数相对磁导率相对于温度的变化率的增加的NiZn系铁氧体和使用其的噪声滤波器。该NiZn系铁氧体由以Fe2O3换算计为47.50mol％以上48.60mol％以下的Fe、以ZnO换算计为29.00mol％以上30.10mol％以下的Zn、以CuO换算计为5.50mol％以上6.50mol％以下的Cu、以NiO换算计为14.80mol％以上18.00mol％以下的Ni构成，Fe2O3、ZnO、NiO、CuO的合计量为100mol％，其中，Fe2O3和ZnO的合计量为77.00mol％以上78.50mol％以下。
