Environmental
Air flow: 38 CFM minimum (sea level)*
Temperature
    Operating: -25°C to +55°C (sea level)*
    Storage:  -55°C to +85°C
Humidity: 5-95%, non-condensing
Random vibration: 7.6 g
    Frequency / Level
    20 Hz / 0.04g2/Hz
    1000 Hz / 0.04g2/Hz
    2000 Hz / 0.01g2/Hz
Shock
    x and y axes, 50g,11 ms, half-sine
    z axis, 30g, 11 ms, half-sine
Altitude
    Operating: <30,000 ft* (sea level)
*As altitude increases, air density decreases and, therefore, the cooling effect of a particular number of CFM decreases. Different limits can be achieved by trading among altitude, temperature, performance, and airflow. Contact Mercury for more information.
