Choke Coils for PFC PFC Series Conformity to RoHS Directive Development Concept This small and thin PFC choke coil utilizes a power factor-improving circuit, which is suitable for the smaller and thinner electronic devices of recent years. MATERIAL Thanks to the development of an optimized core shape and materials, the choke coil has DC superimposition characteristics suitable for the design of various types of electronic devices. Optimized materials have been selected, and at the same time a small and thin PFC core with TDK's proprietary core shape has been developed. The product line-up has...
