Wet Tantalum Caps Operate to 200 Degrees C with 1,000 Hour Life

January 15, 2018 by Paul Shepard

Vishay Intertechnology, Inc. today introduced a new series of HI-TMP® tantalum-cased, hermetically sealed wet tantalum capacitors with high temperature operation to +200 °C. Offering increased reliability for industrial and oil exploration applications, T34 series axial-leaded through-hole devices deliver increased mechanical shock and vibration withstand ability, along with longer life.

Optimized for timing, filtering, energy hold-up, and pulse power applications, the capacitors released today offer high vibration (sinusoidal: 80 g; random: 54 g) and mechanical shock (500 g) capabilities while providing a long life of 1,000 hours minimum at +200 °C.

Offered in the A, B, C, and D case codes, the T34 series features voltage ratings from 25Vdc to 125Vdc, a wide capacitance range from 10μF to 470μF — with extensions planned to match current Vishay Sprague 134D series ratings — and capacitance tolerance of ±10% and ±20% standard.

The devices operate over a temperature range of -55 °C to +85 °C, to +200 °C with voltage derating, and provide maximum ESR down to 0.75Ω at 120Hz and +25 °C. RoHS-compliant, halogen-free, and Vishay Green, the capacitors offer both lead (Pb)-free and tin/lead (Sn/Pb) terminations.

Samples and production quantities of the T34 series are available now, with lead times of 12 weeks for larger orders. Pricing for U.S. delivery only starts at $100 per piece.
