SOLID ELECTROLYTIC CAPACITOR AND METHOD FOR PRODUCING THE SAME |
摘要 |
A solid electrolytic capacitor comprising a capacitor element obtainable by compressing a porous valve-acting metal substrate having on the dielectric film surface thereof a solid electrolyte layer containing an electrically conducting polymer in the thickness direction, wherein assuming that the maximum thickness and the minimum thickness of the electrically conducting polymer layer including the substrate before the compression are Hamax and Hamin, and the maximum thickness and the minimum thickness of the electrically conducting polymer layer after the compression are Hbmax and Hbmin, the percentage decrease DeltaH in the difference of thickness represented by the following formula is preferably from 5 to 95%: Formula (I). The thin solid electrolytic capacitor element of the present invention, which can be stably produced with a small variety in shape, enables fabrication of a solid electrolytic multilayer capacitor having a high-capacitance and small-size with a low height, which, free from short-circuit failure, exhibits stable performance. |
