ABSTRACT:
An interchangeable, plug-in, in-line module for attenuating electrical noise wherein a plurality of plug-in terminals are electrically coupled to an attenuating circuit in the form of a filter network array including a plurality of discrete components electrically interconnected by conductive traces or printed circuits formed on an insulating board to facilitate a plug-in connection to an electrical system. The attenuating circuit is electrically connected to a conductive retainer which is adapted to receive and retain a plastic motor end cover therein and to make electrical contact with a conductive frame member of the motor. The attenuating circuit includes four ferrite choke beads each having axial through holes or bores through which through-connectors of the terminals pass. The choke beads are supported by an insulating carrier so that the through-connectors can be electrically coupled to the conductive traces.
