Toroidal chokes

Current compensated toroidal chokes

Proudově kompenzované tlumivky

Current compensated toroidal chokes are made on the ferrite toroidal cores with a high permeability. The choke has two symmetrical coils with the same number of turns and they are connected so that the electrical current going through can make opposite magnetic fields.The chokes are used in the suppression filters (suppression of the asymmetrical component part of the interference voltage) for the suppression of the machine line connectors, suppression of the switchboards, signaling devices, control systems etc. The suppression zone ranges from 0,01 MHz to 100 MHz. The chokes are made non-encapsulated (the open version) and encapsulated for using on the PCB´s.

Power toroidal chokes

Power toroidal chokes are made on the iron powder or iron toroidal cores with a high magnetic induction. The chokes consist of one or more coils usually made of varnished conductor or of a wire because of current-carrying capacity. They are meant for suppression of interference symmetrical component part in electrical equipment. The chokes are used in suppression filters for suppression of lighting phase advancer, electric switchboards, control circuits with triaces, thyristors and switching transistors etc. The suppression zone ranges from 0,01 to 10MHz. The chokes are made non-encapsulated (the open version) with free outlet or with base mounting plate for using on the PCB´s.
