WE-CFWI High Current Coupled Flatwire Inductors

Würth Elektronik WE-CFWI High Current Coupled Flatwire Inductors are equipped with two identical flat wire windings for high current capabilities and ultra-low DCR for the best possible efficiency. This series also offers low inductance drift over temperature. Würth Elektronik WE-CFWI inductors are ideal for use in high power switching regulators, 1:1 flyback converters, switching regulators with second unregulated output voltage, battery cell charging balancer, and buck-boost, SEPIC, ZETA, and Ćuk converters.
