ST
Vishay Tansitor
SuperTan® Wet Tantalum Capacitors
with Hermetic Seal
FEATURES
• Very High Capacitance
• 10 to 1800mF
• 25 to 125VDC
• - 55∞C to + 125∞C
• Very Low ESR
• High Ripple Current
Vishay Tansitor’s 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 impedance
restrictions.

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 indus-
tries and whenever there is a space problem.

The peak reverse voltage does not exceed 1.5V and the
peak current times the duration of the reverse transient
does not exceed 0.05 ampere seconds. In addition, the
repitition frequency of the reverse voltage surge is less than
10Hz.
