ABSTRACT:
An improved capacitor, especially of the tantalum capacitor type, wherein a very small particle silver metal powder is impregnated into a porous metal anode member, say of tantalum. The resulting capacitor has a much reduced resistance in the non-dielectric components of the capacitor without any substantial decrease in the desirably-high reistance across the dielectric component of the capacitor. The process of forming such a capacitor is relatively inexpensive and allows one to avoid a number of manufacturing steps and reduce the manufacturing cost of the improved capacitor even though it contains a relatively large amount of silver metal.
