Solid electrolyte capacitor mfr. esp. tantalum capacitors - where anode is formed by stack of thin sintered tantalum discs

摘要

Several modular anode discs are made by sintering a metal powder. The discs are made into a stack to obtain an anode; and an electric connection, esp. a wire, is attached to the stack, which is then subjected to a second sintering operation. The connector wire may be located on the periphery of the stack, or in coaxial holes in the discs. The connector wire is pref. welded to the top and bottom discs in the stack or to all of the discs; and a powder may be located between the wiRe and the discs. The discs, wire and powder pref. all consist of tantalum. Capacitors with optimum properties are obtd. at relatively low cost.
