C-cores made from amorphous Fe-based alloys offer an interesting combination of a
high saturation flux density and low magnetization losses.

The main applications for amorphous c-cores are storage chokes or power factor correction (PFC)
chokes in the frequency range of about 20 to 50 kHz. The relatively high operational induction and
the low losses enable the design of size-optimized solutions.
