301 power inductors

SMD Power Choke (301 Series)

West Coast Magnetics’ 301 series is designed to be used as a power inductor in switchmode power supply applications. These power inductors combine high current handling capability in a low profile SMD package. This inductor has lower EMI than drum core style inductors. Many part numbers can be used as a coupled inductor to accomodate multiple outputs.
