Ferrites

Power Magnetics supplies a wide variety of Ferrite Cores for almost any application. Our product range includes:

E-Cores

With a rectangular cross-section and available in a range of sizes from less than 10mm up to 65mm. The most popular sizes are EE25x6.5, EE42x15, E42x20, E55x21 and E65x27.

ETD Cores feature a circular centre pole and are manufactured to IEC Standards. These cores are intended for use in Transformers and Inductors. They are available in five sizes: ETD29, ETD34, ETD39, ETD44 and ETD 49.

PQ Cores

Designed in Japan for applications requiring compact transformers operating at up to 200KHz. We supply sizes from PQ 20×16 to PQ 35×35.

RM Cores

Rectangular Module (RM) Cores are small and compact and have application in impulse transformers, storage chokes, filters and DC converters.

Toroids

Available in high permeability material suitable for use in common mode inductors in EMC filters.

U Cores

For use as building blocks in assembling KW rated transformers and heavy current chokes.
U126 | U102 | U101 | U100 | U93 | U80 | U63 | U60 | U15

Bobbin Cores

Intended for use in inductors where high frequency ripple current is superimposed upon a DC bias current such as the output smoothing inductor in a power supply. Sizes range from 4mm to 56mm in diameter.
