Cores are primarily found in inductors, transformers and noise-reduction components. Ferrite magnets are mostly used in small motors and speakers. TDK also makes powerful rare-earth magnets. TDK produces a diverse line of capacitors, inductors, filters and other circuit components. Ceramic products are composed of fine layers of electronic materials.
Some components target the unique demands of high-frequency circuitry in mobile phones.
Assembled components signify transformers, inductors and other miniature devices made up of individual elements.
