Abstract
A ferrite composition includes a main component that includes more than 44.0 mol % to 50.0 mol % or less of an Fe compound, 5.5 to 14.0 mol % of a Cu compound, 4.0 to 39.0 mol % of a Zn compound, and a balance of less than 40.0 mol % of a Ni compound. The ferrite composition further includes a subcomponent that includes, with respect to 100 parts by weight of the main component, more than 3.0 parts by weight to 13.0 parts by weight or less of an Si compound, more than 2.0 parts by weight to 10.0 parts by weight or less of a Co compound, and 0.25 to 5.00 parts by weight of a Bi compound. A weight ratio of the content of the Co compound to the content of the Si compound is 0.4 to 2.9.
