Ferrites are a class of ceramic ferromagnetic materials that by definition can be magnetized to produce large magnetic flux densities in response to small applied magnetization forces. Originally referred to as "magnetic insulators," ferrites were first used as replacements for laminated and slug iron core materials in low loss inductors intended for use above **0 kilohertz (kHz). At these frequencies, laminated and slug iron are plagued by excessive eddy current losses whereas the high volume resistivity of ferrite cores limit power loss to a fraction of other core materials. Today, Tai-Tech ferrites are the core material of choice for modern high density switch mode power supply and pulse transformer design.
