A module containing a plurality of active capacitors and a sacrificial capacitor is provided. The active capacitors and sacrificial capacitor are aligned along a horizontal direction so that the side surfaces of their cases are parallel to each other. The particular arrangement of the active capacitors and sacrificial capacitor results in a module configuration where the anode terminations for the active capacitors and an external component of the lead frame for the sacrificial capacitor are coplanar so that the module can be mounted to a circuit board via the anode terminations and the external component of the lead frame in a mechanically and electrically stable manner. Further, the center of gravity of the module in the length and/or width directions can be located at a midpoint of the overall module length and/or width, which enhances the stability of the module when mounted to a circuit board.

Solid electrolytic capacitor module with improved planarity

Surface mount electrolytic capacitors are provided with anode and cathode terminations having respective first termination portions provided on the bottom surface of a molded package in a generally coplanar configuration. A second cathode termination portion is bent in a generally perpendicular fashion to the first cathode termination portion and may then be adhered to the external cathode layer of a capacitor body. A second anode termination portion is bent in a generally perpendicular fashion to the first anode termination portion and may then be welded to an anode wire connected to and extending from the capacitor body. An insulation pad may be provided between the first anode termination portion and the capacitor body to prevent device shorting. A planar termination frame may be provided to form the electrolytic capacitors of the present subject matter. Additional embodiments of the disclosed technology include additional termination portions to effect wrap-around surface-mount anode and cathode terminations.
