Profile: Power Magnetics supplies magnetic components. We stock coil formers & clips, mounts & headers, iron powder cores, nanocrystalline cores and many types of ferrite, including E cores, ETD & RM cores, PQ cores, U cores, toroidal cores, ferrite rods & ferrite bobbin cores. Powder alloy cores are manufactured from a highly compressed powdered ferrous alloy. Small air gaps are distributed evenly throughout the core material and this acts in a similar way to gapping a ferrite core, by reducing core saturation at higher levels of current. Our rectangular module (RM) cores are small & compact and have application in impulse transformers, storage chokes, filters & DC converters.
