An encapsulated filtered feedthrough assembly for an implantable medical device including a ferrule, an electrical insulator coupled to the ferrule, a printed circuit board (PCB), a feedthrough conductor extending through the electrical insulator and the PCB, and a capacitor coupled to the PCB. The encapsulated filtered feedthrough assembly can include a mold defining an opening and located with respect to the printed circuit board such that at least a portion of the capacitor is positioned within the opening. A first non-conductive material can underfill the capacitor and a second non-conductive material can be backfilled into the mold to encapsulate the capacitor.

Method of making an encapsulated filtered feedthrough for an implantable medical device

A filtered feedthrough assembly for an implantable medical device comprises a ferrule, an electrical insulator coupled to the ferrule by a connection element, a plurality of feedthrough conductors extending through the electrical insulator, a printed circuit board (PCB), and plurality of capacitors. The PCB is coupled to the ferrule or the electrical insulator, and includes one or more ground layers and a plurality of vias. The connection element is electrically coupled to the ground layer through the vias. The capacitor has a ground terminal electrically coupled to the ground layer through at least one of the vias, and a conductor terminal electrically coupled to the feedthrough conductor.
