ABSTRACT:
A filtered connector comprises a low pass filter device located, in part, within a metal header, at least one electrode of the filter being soldered to the header. A connector pin passes through the filter. The header forms a shield for EMI radiated from the pin and serves also as a ground conductor for the one electrode. An EMI electrically conductive gasket between a housing and the header provides RF shielding between the two. The pin is supported within the housing and header by a dielectric plug which passes through an aperture in the housing and into an opening in the header, and is connected to the remaining electrodes of the filter device. The ends of the pin extending from the filter are shielded from each other by the header, gasket, and housing while the filter is grounded to the housing by the header and gasket.
