1kW PC Mount transformer

Shaped Foil Inductor (319 Series)

WCM’s 319 series inductors are designed for use in buck boost (differential) circuits. Using an improved generation of Shaped Foil Technology, this inductor series has lower core and winding losses than competing products, especially at frequencies over 10 kHz and ripple current magnitudes of 5% and higher. The 319 series is an industry leading low cost, high performance inductor.

**patent pending on the winding technology used in this design.
