Specified and 100% production tested.
A military RETS electrical specification available on request.
Specified, but not 100% production tested. These limits are not used to calculate average outgoing quality levels.
The average temperature coefficient is defined as the maximum deviation of reference voltage at all measured temperatures between
the operating T MAX and T MIN , divided by T MAX –T MIN . The measured temperatures are ? 55°C, ? 40°C, 0°C, 25°C, 70°C, 85°C, 125°C.
