The ferrite core is made up of iron oxide (Fe2O3) plus one or more additional metal oxides or carbonate compounds (such as manganese, zinc, nickel,
and magnesium). Ferrite raw materials are compressed, then sintered at high temperatures, and machined to generate a completed magnetic core that
matches the application's requirements.

of magnetic materials, ferrite has high magnetic permeability, high
resistance across a wide frequency range, and low eddy current loss.
