    Abstract: A feedthrough capacitor filter assembly includes a capacitor having first and second sets of conductive electrode plates embedded within an insulative or dielectric body, and a leak detection vent for facilitated hermetic seal testing prior to use. At least one feedthrough terminal pin extends through the capacitor in conductive relative with the first set of electrode plates, and an outer ferrule is mounted about the capacitor in conductive relation with the second set of electrode plates. A hermetic seal is seated within the ferrule at one side of the capacitor to prevent leakage of fluid through the filter assembly. The hermetic seal is spaced from a face of the capacitor to form a gap therebetween.
