Vishay Tansitor
Wet Tantalum Capacitors with Hermetic Seal
FEATURES
• Very High Capacitance
• 150 to 4700mF
• 6 to 15VDC
• - 55 ºC to + 85 ºC
Vishay Tansitor’s STArepresents a major breakthrough in Wet
Tantalum capacitor technology. Its unique cathode system, also
used in the ST, provides the highest capacitance per unit
volume available. The STA combines the inherent reliability of
wet tantalum with the capacitance stability of solid tantalum,
and there are no circuit impedance restrictions. The range is
exceptionally well suited for low voltage filtering and energy
storage applications.

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

c) The peak of the applied AC ripple and the applied DC
voltage must not exceed the DC votage rating of the
capacitor.
d) Ripple current ratings by part number at 85 ºC and 40kHz
are included in the table. Ripple current correction factors
for other temperatures and frequencies are given on the
next page.
