An Excellent Duet!

Coupled Inductors

The WE-MCRI is an innovative molded coupled inductor with fully automated bifilar winding process. It offers an almost ideal coupling coefficient up to 0.995. The WE-MCRI features a soft saturation behavior with its crystalline core structure and distributed air gap.

The coupled inductor range includes high voltage isolation versions up to 2 kV, low profile types and versions with various turns ratios.
