RF Chip Wirewound Inductors (TRCM)
RF Chip Wirewound inductors Go To Extremes Superior Performance. Miniaturisation of today's electrical and electronic devices requires component manufacturers to increase the performance of components without increasing footprint. DeMint (TRCM) series utilities wirewound technology that offers wide Pad inductor with the highest SRF carrying capability, highest usable frequency range, and the best Q factor of the narrow pad (TREM) and (TREC) series.
The latest wirewound chip inductor (TRCM) series offers improved performance in the same compact molded case size. These series conform to the RoHS directive and Lead-free. Custom parts are available on request. DeMint will also produce devices outside these specifications to meet specific customer requirements, please contact our sales for more information.
