A surface mount capacitor ( 10 ) and method for making the same. A solid slug or pellet anode body ( 1 ) is encapsulated in a case ( 6 ) of insulating material. An anode and cathode termination pair ( 2, 3 ) are formed with surface mount mounting portions on one side of the case ( 6 ). An electrical connection ( 4 ) is made from the cathode termination ( 2 ) to a cathode on pellet ( 1 ) through the case ( 6 ). An electrical connection ( 7 ) is made between an anode associated with the pellet ( 1 ) and the anode termination ( 3 ) externally of the case ( 6 ). The external connection ( 7 ) allows improved volumetric efficiency by freeing up space in the case ( 6 ) for a bigger pellet ( 1 ). The method includes mass producing these capacitors ( 10 ) by mounting a plurality of pellets ( 1 ) on a lead frame ( 11 ) with pre-formed anode/cathode termination pairs ( 2, 3 ), at least substantially encapsulating the plurality of mounted pellets ( 1 ) and each pellet's associated anode and cathode, singulating the encapsulated pellets ( 1 ) to expose a portion of the pellet anode, and applying the electrical external conductive path ( 7 ) between pellet anode and anode termination ( 3 ). |
