SMD Wet Ta Capacitor for Avionics and Aerospace Applications

March 29, 2016 by Jeff Shepard

Vishay Intertechnology, Inc. today introduced a new tantalum-cased wet tantalum capacitor with a glass-to-tantalum hermetic seal that is the industry's first in the compact 9 mm by 7.1mm by 7.4mm C case code. For avionics and aerospace systems, the T22 combines a reverse voltage of 1.5V at +85 degrees C with increased thermal shock capability of 300 cycles in a surface-mount package.

As a replacement for axial leaded through-hole capacitors, the device released today reduces PCB space requirements while providing a more reliable alternative to SMD devices for timing, filtering, energy hold-up, and pulse power applications in power supplies for space and avionics equipment. Featuring a high-reliability design, the capacitor offers high vibration (sinusoidal: 50g; random: 27.8g) capability.

The T22 features voltage ratings from 50Vdc to 125Vdc, capacitance from 10μF to 68μF, and capacitance tolerance of ±10% and ±20% standard. The device operates over a temperature range of -55 to +85 degrees C, to +125 degrees C with voltage derating, and provides maximum ESR down to 1.50Ω at 120Hz and +25 degrees C. The capacitor features standard tin/lead (Sn/Pb) terminations, with RoHS-compliant 100% tin terminations available.

Samples and production quantities of the T22 are available now, with lead times of 10 weeks for larger orders. Pricing for U.S. delivery only starts at $35 per piece.
