Ferrite core is a highty magnetic mattial that is widely used in diverse sectors of the electronics irdustry. Ferrite core is an essential element in circuits and electric power transformers, found not only in computers but also tetevision sets and telecommunications, measuring, and other equipment. Ferrite cores display excellent electromagnetic compatibility (EMC), characteristics for noise eliminating and prevention, in machinery circuits and power source lines. It is truly a basic element supporting the electronics industry. JFE Ferrite will respond to advances in electronics, meeting the need for high performance, compactness,and high reliability with superior ferrite cores.
