Vishay Intertechnology has released a new series of HI-TMP surface-mount wet tantalum capacitors with high operating temperatures 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 utilize board space more efficiently and deliver increased reliability for oil exploration and military and aerospace radar applications.
Measuring 9 mm by 7.1 mm by 7.4 mm, the capacitors released today feature a tantalum metal case with 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 and provide a longer life of 2,000 hours at +200 °C, eliminating the need to utilize larger through-hole devices in demanding environments.
The T24 series features 200 °C derated voltage ratings of 45 VDC and 75 VDC, with capacitance values of 33 µF and 10 µF, respectively, 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 2.5 Ω at 120 Hz and +85 °C. The capacitors are RoHS-compliant, halogen-free, and Vishay Green.
