ABSTRACT:
A feed-through filter capacitor assembly is provided to pass a conductor into a housing of an electronic device while maintaining a hermetic seal and filtering spurious radio frequency signals. The assembly is particularly suitable for use in medical implant devices such as pacemakers. The feed-through filter capacitor assembly comprises a conductive bushing forming a cup that receives a filter capacitor body. The cup is located to one side of a pass-through portion including a passageway in which an insulative spacer is mounted. A plurality of wires pass through the filter capacitor body and spacer. The wires are contacted with inner plates of the capacitor and insulated from the bushing. Conductive polymer resin within the cup provides electrical continuity between outer contacts of the capacitor body and the conductive bushing. This arrangement also provides an effective heat sink for the filter capacitor body and protects the filter capacitor body from physical damage. The arrangement of a cup to the side of the pass-through portion allows sizing of the capacitor independently of the size of a housing hole provided to receive the assembly.
