■What is ferrite core?

Ferrite is a magnetic material made from a collection of crystalline compounds containing iron oxide, and there are two main types: soft ferrite and hard ferrite. Tomita Electric is a manufacturer of soft ferrite products. Compared to metallic magnetic materials, it can be used in higher frequency bands and is useful for downsizing and saving energy in various electronic devices. It may be hard to believe, but more than 500 ferrites are used in a single household electronic product. Tomita's products support a comfortable life behind the scenes.
