Vishay's T18 tantalum-cased electrolytic capacitors provide all the advantages of the company's SuperTan® series devices while offering 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. 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 T18 series is offered in the A, B, C, and D case sizes. In the D case size, the devices combine their ultra-high-capacitance with low ESR values down to 0.50 Ω at 120 Hz and +25 °C. 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.
These new capacitors released feature standard tin/lead terminations, with RoHS-compliant 100 percent 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.
