Panasonic’s Metal Composite SMD high Power Choke Coils (PCC) have very low audible noise characteristics and are extremely efficient with low DCR and eddy current loss reduction. Metal composite core material with distributed air-gap and stamped frame coils on some of the series provide near linear inductance vs. current and don’t saturate, while also offering a cost effective design solution.
Panasonic’s R&D succeeded by developing and introducing the market’s top-efficient Iron Powder Power Choke Coils with min. DCR in min. case size and L-value up to 100µH.
