Wet Tantalum SMD HI-TMP Capacitors with Improved Thermal Shock Capability and Longer Life
Vishay Intertechnology has introduced a new series of HI-TMP surface-mount wet tantalum capacitors with high operating temperatures to +200 °C in the compact C case code. The new T24 series is designed to utilize board space more efficiently and deliver increased reliability for oil exploration, and military and aerospace radar applications. It offers a smaller size and footprint than equivalent through-hole and overmolded high temperature devices. The capacitors are RoHS-compliant, halogen-free, and Vishay Green. Moreover, the T24 series features 200 °C derated voltage ratings of 45 VDC and 75 VDC, with capacitance values of 33 µF and 10 µF 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 devices are optimized for timing, filtering, energy hold-up and pulse power applications and 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 capacitors feature a tantalum metal case with a glass to tantalum hermetic seal and their dimensions measures 9 mm by 7.1 mm by 7.4 mm. 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.
