Abstract
A discoidal feedthrough capacitor has its active electrode plates disposed within a dielectric body so that an edge of the active electrode plates is exposed at a surface of a through-hole for a conductive lead. The conductive lead is conductively coupled to the exposed edge of the electrode plates without an intervening conductive termination surface. Similarly, a ground electrode plate set of the feedthrough capacitor may have an edge exposed at the outer periphery of the capacitor for conductively coupling the exposed edge of the ground electrode plate to a conductive ferrule without an intervening conductive termination surface.
