Patent ID: 7289006

Claim:
A localized in-line cable filter system for implementing electromagnetic cable noise suppression comprising: a cable connected to a noise source; said cable comprising a ribbon cable including a plurality of wires extending parallel to each other in a common plane; an electromagnetic interference (EMI) filter disposed near the noise source; said EMI filter including a plurality of EMI filter elements arranged in dual, staggered rows within a housing; said plurality of said electromagnetic interference (EMI) filter elements connected to said ribbon cable; at least one said EMI filter element being implemented with at least one discrete value capacitor; a ferrite core surrounding said cable disposed proximate one side of said housing of said EMI filter opposite the noise source; and a current return path member coupled between said EMI filter element and the noise source; said current return path member shunting noise current back to the noise source; said current return path member comprising a sheet metal member extending through a generally rectangular slot defined in said housing and in a plane adjacent to said common plane of said ribbon cable; said current return path member having a minimized path length for connecting to the noise source; and said housing containing said at least one discrete value capacitor implementing one said EMI filter element, said connection of said EMI filter elements to said ribbon cable and a portion of said current return path member.
