SOLID ELECTROLYTIC CAPACITOR AND METHOD OF MANUFACTURING THE SAME |
摘要 |
A solid electrolytic capacitor comprising; an electrolyte comprising a conductive polymer i) having a repeating unit of at least one compound selected from a heterocyclic compound and ii) containing as a dopant at least one anion selected from a naphthalenesulfonate, an alkyl naphthalenesulfonate at least one of hydrogen atoms on the naphthalene ring of which has been substituted with an alkyl group having 1 to 12 carbon atoms, an anthraquinonesulfonate, and an alkyl anthraquinonesulfonate at least one of hydrogen atoms on the anthraquinone ring of which has been substituted with an alkyl group having 1 to 12 carbon atoms; said electrolyte being provided on a valve metal on the surface of which a dielectric film is formed by anodic oxidation or anodic chemical conversion. Also disclosed is a method of manufacturing the solid electrolytic capacitor, in which the electrolyte is formed by electrolytic polymerization. |
