A feedthrough assembly may include a ferrule defining a ferrule opening, a capacitive filter array at least partially disposed within the ferrule opening, and a feedthrough at least partially disposed within the ferrule opening. Acid groups are bound to the hybrid inorganic-organic polymer through an interaction with the implanted metal cations. The results of such analysis can help users, managers and organizations to improve their competitive position in their respective fields. Accordingly, product loss is reduced and product yield is increased. Only the mounting studs need to be threaded to match the loads.
