CHOKES

Wound on M6 cores with factory adjusted gap. The chokes suitable for capacitor input filters should not be used in a choke input filter configuration. Chokes for choke input filters are listed below. Plate chokes for use in parallel feed amplifiers are specially designed using a two chamber bobbin and additional insulation to maximize the self resonance frequency. Bifilar wound balun chokes and other special chokes can be supplied on a custom design basis.  All our chokes are normally supplied in an open frame (Style "O") package.  Fully shrouded (Style "S") is available for a small extra charge.

For tapped equalizer chokes see EQ Inductors
