A capacitor 30 containing a solid electrolytic capacitor element 33 that includes an anode 16 , dielectric 36,37 and a cathode 38 that includes a solid electrolyte is provided. An anode lead 63 extends from the anode and is electrically connected to an anode termination 51. Likewise, a cathode termination 72 is electrically connected to the cathode. The cathode termination 72 contains an upstanding portion 74 that is oriented generally perpendicular to the lower surface of the capacitor element 33, and first 75 and second 73 planar portions that are oriented generally parallel to the lower surface of the capacitor. The first and second planar portions are interconnected by a folded region so that the first portion 75 is positioned vertically above the second portion 73. Thus, after encapsulating the capacitor element with a molding material 58 , the second planar portion remains exposed for subsequent connection to an electrical component. However, due to its higher vertical position, the first planar portion can be completely encapsulated by the molding material. In addition, the upstanding portion 74 of the cathode termination is also substantially encapsulated by the molding material. By encapsulating both planar and upstanding portions of the cathode termination with the molding material, the likelihood of delamination is reduced even if a portion of the molding material cracks. This improves mechanical stability and electrical performance. |
