Wet tantalum capacitors are the capacitor of choice for space, military, down-hole drilling, and other high
reliability applications. Vishay is the global leader in this technology and offers the broadest portfolio, as well
as the industry’s leading performance families.
Here are wet tantalum capacitors are the ideal solution for high reliability and harsh six reasons
environment applications:
Vishay wet tantalum capacitor capabilities:
• Capacitance values from 1.7 µF to 72 000 µF
• Voltage range from 6 V to 150 V
• 300 thermal shocks, -55 ºC to +125 ºC
• 80 g sine wave vibration, 54 g random vibration
• Both tin / lead and 100 % tin RoHS-compliant terminations are available
• Meet NASA radiation-tolerant testing requirements
• Can operate at altitudes up to 150 000 feet
• Production experience since 1926
• Vishay wet tantalum technology is the best of Sprague, Philips, Tansitor, Mallory,
Low DC leakage. For example,
the 135D series offers DCL
values down to 1 µA at 25 °C
• This increases battery life and
reduces power consumption
• The internal electro-chemical
process also means this value
will improve over the life of the
part, further optimizing circuit
• This enables designers to
achieve more capacitance per
specified and rated voltage
• Solid tantalum equivalents
require up to 50 % derating
Withstand up to 3 V of reverse
capacitors with a tantalum
• Solid tantalum or silver
exhibit catastrophic failure
High temperature operation.
For example, 230 °C for the
• Most wet tantalum families
are restricted to +125 °C
High ripple currents. For
example, 2360 mA at 40 kHz
for the 10 V, 750 µF 135D
• This stops the device from
overheating and subsequently
• It means they significantly
No aging or reforming required
• They also have an unlimited
shelf life when stored in a
successfully used in avionics
and space applications for
