Chip capacitors from Vishay for space level applications

CWR06 and CWR16 solid tantalum chip capacitors from Vishay are now approved to the "T"-level requirements of MIL-PRF-55365 for space-level applications. Vishay says CWR06 and CWR16 have undergone 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 °C, and + 85 °C. 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 ohm 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.

Availability: T-level-rated capacitors are available now.
