Solid electrolytic capacitor and method for manufacturing the same |
摘要 |
A solid electrolytic capacitor using a conductive polymeric compound as a solid electrolyte is disclosed, wherein a powder is dispersed in the conductive polymer to provide unevenness on the surface of the solid electrolyte, thereby increasing the surface area, whereby a mechanical adhesion between the solid electrolyte and a cathode conductor layer is increased. The conductive polymer comprises a first conductive polymer layer which contacts a dielectric layer at an anode body side, and a second conductive polymer layer which contacts the cathode conductor layer side, and the powder is dispersed in the second conductive polymer layer. By this constitution, tan delta and an equivalent series resistance (ESR) of the solid electrolytic capacitor are decreased. |
