Inductors
Large-Current Power Inductors MPLCH Series
Overview
KEMET’s MPLCH Series of metal composite inductors is
ideal for use in DC to DC switching power supplies. The
combination of composite core material and round wire
allows these inductors to provide high permeability, low
DC resistance and high inductance.
