A capacitor for powering an implantable medical device is described. The capacitor includes a casing having contoured surfaces to more closely conform to body contours. This means that the anode housed in the casing must also have a contoured shape substantially matching that of the casing. Accordingly, the anode is comprised of a pressed pellet having a surrounding peripheral edge extending to spaced-apart first and second major face walls. An anode lead wire comprises an embedded portion extending into the anode pellet. First and second channel-shaped recesses aligned with each other extend into the anode pellet from the first and second major face walls to intersect with the embedded lead wire portion. The first and second channel-shaped recesses also extend to opposed locations at the surrounding peripheral edge of the anode pellet. The anode pellet is bent at the aligned first and second channel-shaped recesses to provide a right anode pellet portion electrically connected to a left anode pellet portion by the embedded lead wire portion. The thusly contoured anode pellet has an anatomical shape that matches that of the contoured casing to provide an implantable capacitor that is volumetrically efficient.

A capacitor carrier assembly includes a carrier, a capacitor disposed in the carrier and electrically conductive connection terminals. The connection terminals support the carrier with respect to another electronic component or device such as a printed circuit board, retain individual carrier portions in an assembled configuration, and provide an electrical connection between the capacitor and the electronic component. Each connection terminal includes an elastic member that protrudes from a surface of the connection terminal and engages the carrier, and regions of serrations provided on opposed edges of the terminal that engage the carrier, and a flange that protrudes from the surface in a direction perpendicular to the first surface. An edge of the flange includes an insulation displacement contact (IDC) joint for connection to the capacitor leads.
