About Soft Magnetics

Soft ferrite, molypermalloy and nanocrystalline materials concentrate magnetic fields to transmit electrical signals and power over a wide frequency range. Ferrite cores are the primary products for inductive components, which are used in switch- mode power supplies for electronics. Soft magnetics are also key components in many emerging markets and applications.
