Claim:
A modular EMI filtered terminal assembly, comprising: a) a hermetic terminal subassembly comprising: i) a ferrule comprising a ferrule sidewall extending from a first ferrule end to a second ferrule end; ii) an insulator comprising an insulator body having a first insulator surface spaced from a second insulator surface by an outer insulator sidewall with at least one insulator via extending through the insulator body from the first insulator surface to the second insulator surface thereof, wherein the insulator is hermetically sealed to the ferrule with the first insulator end adjacent to the first ferrule end and the second insulator end adjacent to the second ferrule end; and iii) at least one conductor extending through the at least one insulator via in a hermetic relationship therewith; and b) a feedthrough capacitor subassembly comprising: i) a conductive modular cup comprising a cup sidewall extending from a webplate to an opposite open cup end; ii) a feedthrough capacitor comprising a dielectric body having a first dielectric surface spaced from a second dielectric surface by an outer dielectric sidewall with at least one dielectric via extending through the dielectric body from the first dielectric surface to the second dielectric surface thereof; iii) at least one first electrode plate supported by the dielectric body in spaced relation with at least one second electrode plate, the at least one first electrode plate being electrically connected to the at least one conductor by a first conductive material contacting a first metallization at the at least one dielectric via, the first electrode plate being spaced from a second metallization at the outer dielectric sidewall, and the second electrode plate being electrically connected to the cup sidewall by a second conductive material contacting the second metallization at the outer dielectric sidewall, the first electrode plate being spaced from the first metallization at the dielectric via and the at least one conductor; and iv) wherein the feedthrough capacitor is at least partially disposed within the modular cup with the first dielectric surface adjacent to the webplate and the second dielectric surface adjacent to the open cup end; and c) an electrical connection from the modular cup of the feedthrough capacitor subassembly to the ferrule of the hermetic terminal subassembly, wherein the second dielectric surface adjacent to the modular cup open end is a greater distance spaced from the first insulator end and from the first ferrule end than that of the first dielectric surface and the cup webplate spaced from the first insulator and ferrule ends.
