Patent ID: 7570479

Claim:
A solid electrolytic capacitor comprising: at least one capacitor element, and each one of the at least one capacitor element having a body being coiled and having at least one anode foil, at least one cathode foil and at least two separator layers individually formed between the at least one anode foil and the at least one cathode foil; and at least two leads connecting respectively to the at least one anode foil and the at least one cathode foil of the body; and an insulating housing with a base having a top having at least one opening that is sealed after the at least one capacitor element is mounted in the base; a bottom having an edge; and at least one set of holes being defined through the bottom and each one of the at least one set of holes allowing the at least two leads of each one of the at least one capacitor element to extend respectively out; at least one set of sealant-filled recesses, and each one of the at least one set of the sealant-filled recesses being formed in the bottom respectively concentric with one of the at least one set of holes, communicating respectively with a corresponding set of holes and being filled with sealant; and at least one chamber being formed in the base and communicating respectively with the at least one opening and the at least one set of the holes and each one of the at least one chamber receiving each one of the at least one capacitor element.
