Abstract
A ferrite composition includes a main component and a sub-component. The main component includes 10.0 to 38.0 mol % of a Fe compound in terms of FeO, 3.0 to 11.0 mol % of a Cu compound in terms of CuO, 39.0 to 80.0 mol % (excluding 39.0 mol %) of a Zn compound in terms of ZnO, and a balance of a Ni compound. The sub-component includes 10.0 to 23.0 parts by weight of a Si compound in terms of SiO, 0 to 3.0 parts by weight (including 0 parts by weight) of a Co compound in terms of CoO, and 0.1 to 3.0 parts by weight of a Bi compound in terms of BiOwith respect to 100 parts by weight of the main component.
