Abstract
An electrical connector (10) and a filter insert (60) include a planar inductor (62) having recesses (63) containing MOV voltage surge protectors (72) fitted therein with conductive traces (68) formed on the surface of the inductor connecting signal pin portions (50) of contacts (44) that extend through the inductor to the protectors and ground traces (70) that connect the protectors to ground circuits provided by the shell portion (22), the inductor providing an L and the protector providing an internal C to form an LC network filtering out unwanted signal frequency components; the protector (72) operating to connect signal traces to a ground trace in the presence of excessive voltage transients. The insert (60) is dimensioned to fit interiorly of the connector (10). A multi-pin connector is contemplated with a common inductor plate (62) for such connector.
