| Zusammenfassung: | The invention relates to aluminum surface mount capacitors having anode foil anodized in an aqueous phosphate solution.
Aluminum surface mount capacitors containing one or more anode foil coupons are initially anodized in an aqueous phosphate solution in order to produce an anodic oxide film having extreme resistance to hydration and attack by corrosive anions for the purpose of producing surface mount capacitors at high yield and of high stability. |
