Abstract
In one example, a capacitor structure may include a capacitor comprising a surface that defines at least one feedthrough aperture and a ceramic insulator layer attached to the surface. The surface of the capacitor may include a capacitor registration feature, and the ceramic insulator layer may include a ceramic insulator layer registration feature. The capacitor registration feature and the ceramic insulator layer registration feature may cooperate to substantially align the ceramic insulator layer to the capacitor, e.g., prior to the ceramic layer being attached to surface of the capacitor.
Claims14
A capacitor structure comprising:
- a capacitor comprising a surface that defines at least one feedthrough aperture, wherein the surface further comprises at least one capacitor registration feature;
- and
- a ceramic insulator layer attached to the surface, wherein the ceramic insulator layer includes at least one ceramic insulator layer registration feature, and wherein the at least one capacitor registration feature and the at least one ceramic insulator layer registration feature cooperate to substantially align the ceramic insulator layer to the capacitor.
A feedthrough assembly comprising:
- a ferrule defining a ferrule aperture;
- a conductor;
- and
- a capacitor structure disposed within the ferrule aperture, wherein the capacitor structure comprises:
- a capacitor comprising a surface that defines a capacitor feedthrough aperture, wherein the surface further comprises at least one capacitor registration feature, and
- a ceramic insulator layer attached to the surface, wherein the ceramic insulator layer includes a ceramic insulator layer registration feature and a ceramic insulator layer feedthrough aperture substantially aligned with the at least one capacitor feedthrough aperture, wherein the capacitor registration feature and the ceramic insulator layer registration feature cooperate to substantially align the ceramic insulator layer to the capacitor, wherein the conductor passes through the capacitor feedthrough aperture and the ceramic insulator layer feedthrough aperture.
