Nowadays, more and more high-frequency circuits are being used in industrial equipment as well as consumer equipment. With the use

of higher frequencies, silicon steel sheets have become unsuitable for magnetic material used in transformers. Ferrite, its substitute,

delivers reduced core loss at high frequencies and is the optimum material for high-power requirements.

To meet these various demands, we at TDK have employed our ferrite development technologies accumulated over the years and

advanced production technologies to offer large, high-quality cores for high-frequency, high-power power supplies.

The following information includes a wide range of ferrite cores based on PC40 as well as PE22 that delivers the same superior magnetic

characteristics.
