摘要：
A filter feedthrough for an AIMD includes an electrically conductive ferrule. An insulator hermetically seals a ferrule opening with either a first gold braze, a ceramic seal, a glass seal or a glass-ceramic seal. At least one conductive pathway is hermetically sealed to and disposed through the insulator body in non-conductive relationship with the ferrule. A feedthrough capacitor includes at least one active and ground electrode plate disposed within a capacitor dielectric and electrically connected to a capacitor active metallization and a capacitor ground metallization, respectively. At least a first edge of the feedthrough capacitor extends beyond a first outermost edge of the ferrule. At least a second edge of the feedthrough capacitor does not extend beyond a second outermost edge of the ferrule, or said differently, the second edge is either aligned with or setback from the second outermost edge of the ferrule.
