Vishay Intertechnology introduced a new TANTAMOUNT Hi-Rel COTS series of surface-mount solid tantalum chip capacitors for military and avionics applications.
The industry's first such devices to feature a metal case and hermetic sealing to meet the requirements of MIL-STD-202, Method 112, Condition A, the Vishay Sprague T25 series offers low ESR down to 180 mΩ at +25 °C and 100 kHz and is available with surge current testing options in accordance with MIL-PRF-55365.
The devices released today are optimized for timing applications in avionics and munitions systems. For these critical applications, the capacitors offer high reliability with burn-in at rated voltage for a minimum of 40 hours, while their hermetic sealing eliminates any moisture sensitivity.
Offered in the D case code, T25 devices feature a capacitance range from 22 μF to 330 μF over voltage ratings from 16 V to 50 V; capacitance tolerances of ± 10 % and ± 20 %, and an operating temperature range of -55 °C to +85 °C, to +125 °C with voltage derating. RoHS-compliant, the capacitors are available with 100 % tin or tin / lead terminations.
