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.
