STA
Vishay
Wet Tantalum Capacitors with Hermetic Seal
Vishay STA represents 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.
FEATURES
• Very High Capacitance
• 150 to 4700µF
• 6 to 15VDC
• - 55°C to + 85°C
APPLICATION NOTES
a) No continuous reverse voltage permissible.
b) Transient reverse voltage surges are acceptable under
the following conditions:
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 voltage 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.
