ABSTRACT:
A common mode filter with a choke portion and an electrical isolation portion is made up of two core members, each core member having two legs. A first winding is wrapped around the first leg of the first core member to form a first coil of the isolation section, but the secondary coil of the isolation section and both coils of the choke section are formed by a single winding which may be a single wire or may include a portion connected through a circuit board. The ends of the second winding may be shaped so as to form the mating sections of a pair of RJ contacts, while the ends of the first winding may be shaped to form pins for insertion into openings in a LAN interface card, the core structures being positioned in a rear chamber of an RJ connector.
