Common Mode Chokes for EMI suppression

Our single or multiple phase chokes are based on toroidal tape wound cores made of the nanocrystalline softmagnetic material NANOPERM®. They combine high attenuation levels with small build volume.

Compared to conventional ferrite solutions, a size reduction of up to 60% can be achieved!

The design is according to EN60938-1 for 230V and 500V/600V mains voltage.
The standard tolerance of the nominal inductance is +50%/-30%.

Samples and custom specified versions are available upon request (see check list).
