SMD Wet Tantalum Capacitor From Vishay Intertechnology Offers Small Size for Avionics + Aerospace Applications

[Satnews] Vishay Intertechnology, Inc. (NYSE: VSH) has 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 7.1 mm by 7.4 mm C case code.

For aerospace systems and avionics, the T22 combines a reverse voltage of 1.5 V 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: 50 g; random: 27.8 g) capability.

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

Samples and production quantities of the T22 are available now, with lead times of 10 weeks for larger orders.
