Abstract: A solid electrolytic capacitor that includes an anode body, a dielectric overlying the anode body, a solid electrolyte that contains one or more conductive polymers and overlies the dielectric, and an external coating that overlies the solid electrolyte, is provided. The external coating includes at least one carbonaceous layer and at least one metal layer. In addition to the aforementioned layers, the external coating can also include at least one conductive polymer layer that can be disposed between the carbonaceous and metal layers. Among other things, such a conductive polymer layer can reduce the likelihood that the carbonaceous layer will delaminate from the solid electrolyte during use. Further, the notched geometry of the anode body itself is selected to minimize the risk of delamination of the external coating layers from the anode body. This combination of characteristics can increase the mechanical robustness of the part and improve its electrical performance.

The capacitor element includes a sintered, porous anode body; a dielectric layer overlying the sintered, porous anode body; and a cathode overlying the dielectric layer that includes a solid electrolyte. The first and second anode leads each have an embedded portion positioned within the anode body and an external portion extending longitudinally from a surface of the anode body in an x-direction, while the carrier wire is positioned external to the anode body. Further, a first portion of the carrier wire is connected to the external portions of the first and second anode leads, while a second portion of the carrier wire extends longitudinally away from the surface of the anode body in the x-direction. Such an arrangement reduces the ESR and leakage current of the capacitor.
