Life Test Performance

State of the Art, Inc. maintains the established reliability rating of our MIL-PRF-55342 resistors at level S (0.001%/1,000hours). Sota performs >120 million unit hours of life testing in order to maintain these failure rates. A life test failure is defined as a change in resistance value larger than ±2.0% for failure rate maintenance and ± 0.5% for qualification. These life tests are performed at 70°C ambient at maximum operating voltage applied for 90 minutes on, 30 minutes off, for 10,000 hours.
