Abstract
An assembly integrating commercially available capacitors into filtered feedthroughs. A feedthrough assembly comprises a plurality of Input/Output (I/O) conductors, wherein the I/O conductors pass through a hermetic seal such that a first end of the I/O conductors reside on a non-hermetic side of the hermetic seal and a second end of the I/O conductors reside on a hermetic side of the hermetic seal, a printed circuit interconnect substrate residing on the hermetic side of the hermetic seal, and a plurality of ceramic chip capacitors mounted on the printed circuit interconnect substrate, wherein a first end of each capacitor is connected via the interconnect to the second end of an I/O conductor and a second end of each capacitor is connected via the interconnect to a constant voltage level.
