Ferrite Wide Band Choke
The wide band chokes can advantageously be applied in the UHF radio and television sets as well as in engines, ignition sets, etc. in order to reduce the perturbating radiations and to attenuate the non desired noises intervening in the UHF circuits.
In function of the type, the chokes are manufactured with coils of 1.5-2.5-2 x 1.5 threads.
The material of the wire is tinned copper. The ferrite core disposes of 6 axial holes.
