Temperature Cooling Storage Temperature 0 to +45C Free Air Convection -20 to +85C * 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. All specifications are typical at nominal input, full load, and 25DegC unless otherwise noted * 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.
