Solid electrolytic capacitors and method for manufacturing the same |
摘要 |
The present invention relates to solid electrolytic capacitors with low ESRs in the high frequency range and methods for manufacturing the same. The solid electrolytic capacitor induce a porous anode body made of a valve action metal and on the surface of which body a dielectric oxide layer is formed; and a chemically polymerized layer made of conductive polymers which are formed by chemical oxide polymerization on the dielectric oxide layer which are located on the surfaces inside pores of the porous anode body; and an electrolytic polymerized layer made of conductive polymers which are formed by electrolytic polymerization on the dielectric oxide layer which are located on the external surface of the porous anode body; wherein the dielectric oxide layer and the electrolytic polymerized layer are in contact with each other and the chemically polymerized layer and the electrolytic polymerized layer are electrically connected with each other near the contacting parts. |
