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
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
industries and whenever there is a space problem.

APPLICATION NOTES
a. No continuous reverse voltage permissible.
b. The peak of the applied AC ripple and the applied DC
voltage must not exceed the DC voltage rating of the
capacitor.
c. Ripple current ratings by part number at 85 °C and
40 kHz are included in the table. Ripple current correction
factors for other temperatures and frequencies are given
on the next page.
d. Transient reverse voltage surges are acceptable under
the following conditions:
The peak reverse voltage does not exceed 1.5 V and the
peak current times the duration of the reverse transient
does not exceed 0.05 As. In addition, the repetition
frequency of the reverse voltage surge is less than 10 Hz.
