WCM420-10, 20, 30, 40 Medium Power SMPS Switch Mode Transformers

This new series was designed for applications where board space is at a minimum. Featuring a finite element optimized core geometry to equalize flux distribution throughout the core cross section, the WCM420-10, -20, -30 and -40 core and bobbin sets feature outstanding power density at power levels up to 5 kW. This series is also available with two core material options, one for traditional SMPS frequencies up to 500 kHz and a new low permeability MnZn material with very low loss at frequencies over 500 kHz. As usual with WCM geometries, standoff between core and bobbin has creepage and clearance values which will meet the most stringent medical device standards. This series puts out 500 watts to 5,000 watts of power.
