    Abstract: A hermetic terminal assembly for an AIMD includes a shielded three-terminal flat-through EMI energy dissipating filter and a hermetically sealed feedthrough configured to be attachable to the ferrule or AIMD housing. The flat-through filter includes a first shield plate, an active electrode plate, and a second shield plate where the shield plates are electrically coupled to a metallization which in turn is coupled either to the ferrule or AIMD housing. The feedthrough includes an alumina substrate comprised of at least 96% alumina and a via hole with a substantially closed pore and substantially pure platinum fill. The platinum fill forms a tortuous and mutually conformal knitline or interface between the alumina substrate and the platinum fill, wherein the platinum fill is electrically coupled to at least one active electrode plate in non-conductive relationship to the at least one first and second shield plates.

    Abstract: A co-connected hermetic feedthrough, feedthrough capacitor, and leadwire assembly includes a dielectric substrate with a via hole disposed through the dielectric substrate from a body fluid side to a device side. A conductive fill is disposed within the via forming a hermetic seal and is electrically conductive between the body fluid side and the device side. A feedthrough capacitor is attached to the dielectric substrate and includes a capacitor dielectric substrate, an unfilled capacitor via hole including an inner metallization, a set of capacitor active electrode plates electrically coupled to the inner metallization, an outer metallization disposed and a set of capacitor ground electrode plates electrically coupled to the outer metallization. A conductive leadwire is disposed within the unfilled capacitor via hole. An electrical joint connects the conductive fill, the capacitor inner metallization along with the capacitor active electrode plates and the conductive leadwire.
