High Current Inductors photo

High Current Inductors

West Coast Magnetics' 323 series toroidal inductors are designed for switching power applications at frequencies up to 500 kHz This inductor has an outstanding current rating for its size, high reliability, long service life and ability to handle very high peak currents without saturating. The continuous service temperature rating is 200 degrees C.
