Fields of application


Use in interference suppression filters, interference suppression in automobile industries, interference suppression of thyristor controlled equipment and machines, electric machine controls and electronic switching devices.


Description


Interference suppression chokes are toroidal chokes with two windings and with ferrite ring cores. High inductance, low winding capacity, low copper and iron losses, high attenuation for small sized types and a standard grid are characteristics of these chokes. The toroidal core is the geometric ideal shape for the magnetic flux. This results in a low magnetic stray field and low losses. The windings are constructed for low voltage and are wound with a low stray field.
