摘要: A ferrite composition includes a main component having 46.0 to 49.8 mol % of an iron oxide in terms of Fe2O3, 5.0 to 14.0 mol % of a copper oxide in terms of CuO and 6.0 to 32.0 mol % of a zinc oxide in terms of ZnO, and a remainder of the main component is composed of a nickel oxide; and as subcomponents, with respect to 100 wt % of the main component, 0.5 to 6.0 wt % of a silicon oxide in terms of SiO2 and 0.01 to 2.0 wt % of a boron oxide in terms of B2O3. Further, as a subcomponent, 0.01 to 0.17 wt % of potassium oxide in terms of K2O or 0.3 to 2.0 wt % of tin oxide in terms of SnO2 may be included. According to the present invention, the ferrite composition having good initial permeability, good superposed direct current characteristic and comparatively good temperature characteristic of the initial permeability, and achieving low temperature firing; and an electronic component having the ferrite composition can be provided.
