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.

WCM410-60MG Switch Mode Transformer

WCM410-60MG is designed for applications requiring a high level of isolation and is particularly suited to medical devices. Using litz wire to minimize losses at SMPS frequency, this package will support power levels up to 2 kW and has a moderate temperature rise at RMS power levels up to 1 kW. The geometry is suitable for pushpull, full bridge, half bridge and forward converter applications. Flybacks can also be supported with an optional gapped core. The primary windings can be connected in a parallel or series configuration to accommodate different topologies and input voltages. This semi custom product requires the specification of the (Max.) secondary winding, allowing it to support a wide range of output voltages as well as multiple secondary windings.
