Ultra-High-Capacitance Tantalum-Cased Wet Tantalum Capacitors from Vishay

Offered in the A, B, C, and D case sizes, Vishay's T18 tantalum-cased electrolytic capacitors provide reverse voltage of 1.5 V at +85 °C, thermal shock of 300 cycles, and high vibration (sine: 50 g; random: 27.7 g) capability. In the D case size, the T18 devices combine their ultra-high-capacitance with low ESR values down to 0.50 Ω at 120 Hz and +25 °C.

The wet tantalum capacitors are optimized for timing, filtering, energy hold-up, and pulse power applications in power supplies for space and avionics equipment. The through-hole axial capacitors operate over a temperature range of -55 °C to +85 °C, to +125 °C with voltage derating, and offer capacitance tolerance of ± 10 % and ± 20 % standard.

Key Features:

-Enhanced performance, high reliability design
-Terminations: Standard tin/lead (SnPb), 100 % tin available
-T18 tantalum-case electrolytic capacitors provide all the advantages of Vishay’s SuperTan series devices, while offering improved reverse voltage and vibration capability

The capacitors released today feature standard tin/lead terminations, with RoHS-compliant 100 % tin terminations available.

Samples of the T18 series are available now. Production quantities will be available in August 2013, with lead times of 10 weeks for larger orders.
