  • Any of various crystalline or powdered materials whose composition includes ferric oxide and one or more other metals or metal oxides, such as nickel or manganese oxide. Ferrites are often used in pressed and sintered form, and feature very low eddy current losses at high frequencies. Its many applications in electronics include its use in magnetic cores for inductors and transformers, in semiconductors, in permanent magnets, dielectrics, antennas, and in components utilized in communications, radars, control systems, and so on.
