    Inductors

    For high power inductors, NWL’s unique air gap construction techniques result in less audible noise and lower losses. Designs for Common Mode Inductors use nanocrystalline cores to provide state of the art low loss performance. NWL has extensive experience with large AC duty inductors which see high harmonic content.
