SuperTan® Wet Tantalum Capacitors
with Hermetic Seal
Vishay ST represents a major breakthrough in wet tantalum
capacitor technology. Its unique cathode system provides
the highest capacitance per unit volume. The design
facilitates a doubling of capacitance, lower ESR and higher
ripple current rating compared with conventional wet
tantalum products. Moreover, the ST has the capacitance
stability of a solid tantalum capacitor and there are no circuit
The ST is housed in an all tantalum, hermetically sealed case
and is manufactured to withstand hazardous environments.
The ST is used widely in the defense and aerospace
industries and whenever there is a space problem.
Operating Temperature: -55 °C to +85 °C
