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