PROBLEM TO BE SOLVED: To prevent electromagnetic noises entering through a cable into a device or emitted through the cable from the device. SOLUTION: An electrical device having an enclosure in which noise is parasitically induced in a wire located in the interior of the enclosure is disclosed. The electrical device has a plug-in connector for being connected with an external connector at which a transmission line terminates for preventing the induced noise from being emitted from the device enclosure via the transmission line. The electrical device comprises a printed circuit board (PCB) adapted to be mounted adjacent to an opening in a wall of the enclosure, a receptacle, integral with the PCB, configured to mate with the external connector, a first conductive path coupling the transmission line with the wire when mated, and capacitors mounted on the printed circuit board radially disposed around the receptacle and adapted to be electrically coupled to the external connector when mated. The electrical device further comprises a second conductive path coupling the capacitors to a low potential sink. COPYRIGHT: (C)2005,JPO&NCIPI
