VERBESSERTER TANTALKONDENSATOR UND VERFAHREN ZU SEINER HERSTELLUNG
摘要
A method of manufacturing a tantalum capacitor includes compacting tantalum powder about a tantalum anode rod in such manner than the tantalum powder in a region in registry with the tantalum rod is compacted to a density of from about 8 to 10 grams per cc or more, whereas the density of the remaining portions of the tantalum powder mass are compacted to a density of from about 4 to 7 grams per cc. The disclosure further relates to a improved capacitor formed in accordance with the method, as well as to an improved capacitor preform, the capacitor and preform being characterized in that a higher reliability mechanical and electrical connection is effected between the anode rod and the tantalum materials surrounding the rod.
