HI-TMP wet tantalum capacitors offer increased reliability

Vishay Intertechnology has introduced a new series of HI-TMP tantalum-cased, hermetically sealed wet tantalum capacitors with high temperature operation to +200°C.

Designed to offer increased reliability for industrial and oil exploration applications, theT34 series axial-leaded through-hole devices are able to deliver increased mechanical shock and vibration withstand ability, along with longer life.

The T34 series has been optimised for timing, filtering, energy hold-up, and pulse power applications, and offers 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 0.75 Ω 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.
