Claim Text:
1. A solid electrolytic capacitor comprising: a capacitor element that includes a sintered porous anode body, a dielectric that overlies the anode body, a solid electrolyte that overlies the dielectric, and a moisture barrier layer that overlies the solid electrolyte, wherein the solid electrolyte includes a conductive polymer and an organometallic coupling agent that contains an organic chain with at least one reactive group bonded to a metal atom, and further wherein the moisture barrier layer includes a hydrophobic elastomer, wherein the hydrophobic elastomer is a silicone elastomer, wherein the silicone elastomer is formed from a polydimethylsiloxane, polymethylhydrogensiloxane, dimethyidiphenylpolysiloxane, dimethyl/methylphenylpolysiloxane, polymethylphenylsiloxane, methylphenyl/dimethylsiloxane, vinyldimethyl terminated polydimethylsiloxane, vinylmethyl/dimethylpolysiloxane, vinyldimethyl terminated vinylmethyl/dimethylpolysiloxane, divinylmethyl terminated polydimethylsiloxane, vinylphenylmethyl terminated polydimethylsiloxane, dimethylhydro terminated polydimethylsiloxane, methylhydro/dimethylpolysiloxane, methylhydro terminated methyloctylpolysiloxane, methylhydro/phenylmethyl polysiloxane, fluoro-modified polysiloxane, or a combination thereof; an anode termination that is in electrical connection with the anode body; a cathode termination that is in electrical connection with the solid electrolyte; and a resinous casing that encapsulates the capacitor element and leaves exposed at least a portion of the anode termination and the cathode termination.
