Coupled Inductors

TDK Coupled Inductors are designed for use in a diverse range of applications. These compact coupled inductors feature a high saturation current. The modules can be used as coupled inductors in non-isolated DC/DC converter topologies or as transformers in flyback converters. They can also be used as common-mode inductors in power supply lines. TDK Coupled Inductors provide coupling factors up to 99%. The compact robust designs offer functional isolation voltages between the two windings up to 500V.
