WE-CFWI flatwire inductors designed for high currents

Würth Elektronik has developed the WE-CFWI range of coupled flatwire inductors for high-performance switching regulators. The company says the windings can be connected in series and in parallel, allowing the compact, double choke to be used in SEPIC, CUK, or buck/boost converters. The special core material enables high saturation currents of up to 62A, which is four times higher than previously comparable double chokes, according to the company.

Soft saturation, a very tight tolerance inductance, and very low DC resistance with only 10 per cent tolerance is convincing. The leakage inductance of less than 0.5 per cent reduces peaks in start-up currents. Excellent inductance stability over temperature and low DC resistance makes this component particularly suitable for high-performance switching regulators.

This component is available in an extended temperature range up to 150°C and inductance values of up to 17.6μH.
