307 shaped foil chassis inductor

WCM307 Series Shaped Foil Chassis Power Inductor

Available with patented Foil Technology for high ripple, high frequency applications.

WCM307 series power inductors offer exceptional performance in a compact package. These inductors can handle very high DC currents and high AC ripple currents from 60 Hz up to 500 kHz. They offer exceptional reliability with an operating temperature rating of 200C and can be ordered using West Coast Magnetics’ Shaped Foil TechnologyTM.

Our exclusive shaped foil technologyTM combines the low DCR of a foil winding, with the low AC winding resistance of litz wire. For many high ripple, high frequency applications it has significantly lower winding losses than any litz or solid wire winding. Check with WCM’s engineering department to see if it is right for your application.

*Current Rating:
The current values in this table are the approximate Rms current values which will lead to the temperature rise shown at the top of each column. The conditions under which the RMS current value in the table was determined are:

  1. convective heat transfer with no outside cooling,
  2. no core or AC winding losses, effectively a DC current is applied.

For ripple currents exceeding 2% additional margin must be allowed for core and AC copper losses.
