2) BELLCORE TR-NWT-000332. Case 1: 50% Stress, Temperature at
40°C. (Ground fixed and controlled environment)
* These are stress ratings. Exposure of the devices to any of these conditions
may adversely affect long term reliability. Proper operation under conditions
other than the standard operating conditions is neither warranteed nor implied.
All specifications are typical at nominal input, full load, and 25DegC unless
otherwise noted Astrodyne products are not authorized or warranteed for use
as critical components in life support systems, equipment used
in hazardous environments, nuclear controls systems, or other
mission-critical applications.
