coupled flatwire inductors deliver 62A saturation currents

The inductor's windings can be connected in series and parallel, enabling the compact double choke to be used in either SEPIC, CUK or Buck/Boost converters. The core material enables high saturation currents of up to 62A, which is four times higher than with previously comparable double chokes. The inductors boast soft saturation, a tight tolerance inductance and a low DC resistance with only 10% tolerance. Further to this, the leakage inductance of less than 0.5% reduces peaks in start-up currents. The indusctor is available in an extended temperature range up to 150 °C with inductance values of up to 17.6 µH.

The WE-CFWI range has been designed for high-performance switching regulators requiring powerful inductors with stable inductance and soft saturation to cope with high currents.
