摘要：
An EMI/energy dissipating filter for an active implantable medical device (AIMD) is described. The filter comprises a first gold braze hermetically sealing the insulator to a ferrule that is configured to be mounted in an opening in a housing for the AIMD. A lead wire is hermetically sealed in a passageway through the insulator by a second gold braze. A circuit board substrate is disposed adjacent the insulator. A two-terminal chip capacitor disposed adjacent to the circuit board has an active end metallization that is electrically connected to the active electrode plates and a ground end metallization that is electrically connected to the at least one ground electrode plates of the capacitor. A ground path electrically extends between the ground end metallization of the chip capacitor and the ferrule. There is also an active path electrically extending between the active end metallization of the chip capacitor and the lead wire. The active path comprises at least a first electrical connection material connected directly to both the second gold braze and the lead wire, and the first electrical connection material is electrically connected to the active end metallization of the chip capacitor.
