SOLID ELECTROLYTIC CAPACITORS AND METHOD OF MAKING SAME

摘要

A solid electrolytic capacitor has an electrically conductive counterelectrode system that can advantageously be contacted without the use of flux, and can subsequently be used for high temperature applications, without any accompanying deterioration or corrosion difficulties. The counterelectrode system employs a sprayed layer of a high melting tin-lead alloy in contact with a coating of carbon on the solid electrolyte. The tin-lead carbon contacting layer can advantageously have a lead content of 95 percent by weight, thereby insuring a relatively high melting point therefor.
