Wet Tantalum Capacitors Get Down And Oily

Vishay Intertechnology’s HI-TMP tantalum-cased, hermetically sealed wet tantalum capacitors withstand temperatures up to +200°C, making them viable and reliable for industrial and oil exploration applications. 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 25 VDC to 125 VDC, a wide capacitance range from 10 μF to 470 μF 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 120 Hz 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 starts at $100 per piece. For more details, check out the T34 series datasheet.
