ABSTRACT:
A process is provided for making a tantalum capacitor chip which includes a tantalum chip body as well as an anode wire partially inserted into and partially projecting from the chip body. The process comprises the steps of compacting an initial divided amount of tantalum powder into an initial mass portion which is dimensionally smaller than the chip body, and compacting at least one additional divided amount of tantalum powder with the initial mass portion into the chip body. The capacitor chip thus obtained may be enclosed in a resin package to provide a surface mounting type tantalum capacitor.
