Vishay launches new series of surface-mount tantalum capacitors

Vishay Intertechnology, Inc. has introduced a new series of HI-TMP surface-mount, wet tantalum capacitors. The devices offer high operating temperatures of up to +200° C in the compact C case code.

Offering a smaller size and footprint than equivalent through-hole and over-molded, high-temperature devices, the T24 series is designed to use board space more efficiently and deliver increased reliability for oil exploration, military, and aerospace radar applications.

Measuring 9 x 7.1 x 7.4 mm, the new capacitors feature a tantalum metal case with a glass to tantalum hermetic seal. Optimized for timing, filtering, energy hold-up, and pulse-power applications, the devices offer improved thermal-shock capability to 300 cycles. They also provide a longer life of 2,000 hours at +200° C, eliminating the need to use larger through-hole devices in demanding environments.

The T24 series features 200° C derated voltage ratings of 45 and 75 VDC, with capacitance values of 33 and 10 µF, respectively. Also, the capacitance tolerance is ± 10% and ± 20% standard. These devices operate over a temperature range of -55° to +85° C, to +200° C with voltage derating, providing a maximum ESR down to 2.5 Ω at 120 Hz and +85° C.

The capacitors are RoHS-compliant, halogen-free, and Vishay Green Samples and production quantities of the T24 series are currently available for a limited time.
