Wet tantalum capacitors offer high reliability for industrial and oil exploration applications

Vishay Intertechnology has a new series of HI-TMP tantalum-cased, hermetically-sealed wet tantalum capacitors with high-temperature operation to +200C. 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. Optimised for timing, filtering, energy hold-up, and pulse power applications, the capacitors released today offer high vibration (sinusoidal: 80g; random: 54g) and mechanical shock (500g) capabilities while providing a long life of 1,000 hours minimum at +200C. Offered in the A, B, C, and D case codes, the 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 -55C to +85C, to +200C with voltage derating, and provide maximum ESR down to 0.75Ohm at 120Hz and +25C. RoHS-compliant, halogen-free, and Vishay Green, the capacitors offer both lead (Pb)-free and tin/lead (Sn/Pb) terminations.
