To establish reliability for a T-level rating, Vishay’s CWR06 and CWR16 undergo additional testing, tightened raw material control and production lot definition and control, as well as Weibull level C or D failure rate, and 100 % C surge at – 55 °C, + 0 ºC, and + 85 ºC. In addition, the capacitors receive a 100 % visual and x-ray inspection, destructive physical analysis (DPA) and report, and 2,000-hour life test prior to shipment.
For high-reliability applications, the CWR06 offers a capacitance range of 0.10 μF to 100 μF over voltage ratings from 4 WVDC to 50 WVDC, while the CWR16 offers a capacitance range from 0.33 μF to 330 μF over voltage ratings from 4 WVDC to 35 WVDC.
Both devices feature an operating temperature of – 55 °C to + 85 °C, + 125 °C with voltage derating, in eight case codes (A through H). The capacitors offer capacitance tolerance of ± 10 % and ± 20 % standard, with ± 5 % available, and maximum ESR down to 0.9 Ω at 100 kHz.
Offered in tape-and-reel packaging per EIA 481, the CWR06 and CWR16 feature RoHS-compliant gold-plate terminations standard, with solder plated and hot solder dipped terminations also available.
Production quantities of the T-level-rated capacitors are available now, with lead times of 20 weeks for larger orders. Follow Vishay products for military and aerospace applications at http://twitter.com/VishayMilAero.
