Thu, June 10, 2010 Vishay Introduces Industry's First ESCC-4001/023-Qualified, R-Failure-Rate, Thin Film Wraparound Chip Resistors With TCR Down t
MALVERN, PA--(Marketwire - June 10, 2010) - Vishay Intertechnology, Inc. (
Intended for high-reliability military, aerospace, and medical applications with stringent performance requirements, the Vishay Sfernice resistors offer load-life stability of 0.25 % at +/- 70 deg. C for 8000 hours at rated power. Established reliability is assured through 100 % screening and extensive environmental lot testing, through which the devices have been rated for an "R" failure rate level (0.01 % per 1000 hours).
Offered in four case sizes with on-resistance from 100 ohms to 3.01 megohms, the devices are optimized for low-noise applications including precision measurement of loop voltage, blood pressure, and oxygen levels; voltage comparators; plus acoustic and telecommunication equipment in satellites, missiles, submarines, aircraft, blood pumps, and blood monitoring test devices.
The PFRR resistors feature SnPb terminations over a nickel barrier layer that enables operation at temperatures up to + 155 deg. C, and an alumina substrate for high power ratings to 0.50 W at 70 deg. C. The devices offer very low noise of less than -- 35 dB and a low voltage coefficient of less than 0.01 ppm/V. The resistors are offered in waffle pack or tape-and-reel packaging, and they are halogen-free according to IEC 61249-2-21.
Samples and production quantities of the new devices are available now, with lead times of 12 weeks for larger orders. Follow Vishay products for military and aerospace applications at [ http://twitter.com/VishayMilAero ].
