SMD wet tantalum capacitors offer smaller sizes
Vishay Intertechnology has introduced a tantalum-cased wet tantalum capacitor with a glass-to-tantalum hermetic seal that is the industry's first in the compact 9x7.1x7.4mm C case code. For avionics and aerospace systems, the T22 combines a reverse voltage of 1.5V at +85°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 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 50 to 125VDC, capacitance from 10 to 68μF and capacitance tolerance of ±10 and ±20% standard. The device operates over a temperature range of -55 to +85°C, or to +125°C with voltage derating, and provides maximum ESR down to 1.50Ω at 120Hz and +25°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.
