Capacitors with hermetic seals
Vishay Intertechnology Inc. announced the release of a series of tantalum-cased wet tantalum capacitors with glass-to-tantalum hermetic seals.
For high-reliability applications, the 136D devices operate over a temperature range of – 55 Â°C to + 85 Â°C, to + 200 Â°C with voltage derating, and provide low ESR down to 0.44 Î© at 120 Hz and + 25 Â°C.
The 136D capacitors are commercial equivalents of military-style CLR90 and CLR91 devices, which are designed to meet the performance requirements of military specifications MIL-PRF-39006/30 and 39006/31. In addition, the devices released today are equivalent to former Tansitor EQ and ER styles and Kemet T190 and T191 styles.
The wet tantalum capacitors are optimized for timing, filtering, voltage hold-up, and energy storage applications in power supplies and military, avionics, space, and oil exploration equipment.
The devices offer capacitances from 1.7 ÂµF to 2200 ÂµF in C, F, T, and K case codes, and capacitance tolerances of Â± 20 % standard at 120 Hz and + 25 Â°C, with tolerances of Â± 10 % and Â± 5 % available. The 136D series features standard tin/lead terminations, with RoHS-compliant 100 % tin terminations available, and are offered with standard and extended ratings.
