Abstract: A filtered connector 20 includes a housing means 22 having a plurality of terminal members 42 disposed therein with terminal portions 46 extending outwardly thereof, filter means 48 and grounding means 38. Filter means 48 includes a planar inductive substrate 50, a plurality of terminal receiving passageways 58 extending therethrough and configured to receive corresponding ones of the terminal member portions 46. An array of capacitors 60 is disposed on substrate 50, such that each capacitor 60 is associated with a corresponding terminal receiving passageway 58. In the preferred embodiment, each capacitor 60 includes a first or signal electrode 62, a layer of dielectric material 66 having a selected thickness disposed on the first signal electrode over at least most of the exposed surface thereof; and a second or a ground electrode 68 disposed on layer 66, the ground electrode 68 being electrically isolated from the signal electrode and in capacitive relationship therewith.

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.
