High Current Inductors photo

Shaped Foil SMD Inductor shaped foil technology

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

West Coast Magnetics' 308 series power inductors deliver very high performance in a small, light, low cost package. They have been designed to handle very high DC currents and high AC ripple currents from 60Hz up to 500kHz.These inductors offer exceptional reliability with an operating temperature rating of 200C and they can be ordered using West Coast Magnetics' SHAPED FOIL TECHNOLOGYTM.

*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.
