Caution : The specifications above the Table define levels at which permanent damage to the device can occur. Function operation is not guaranteed under these conditions. Operating at absolute maximum conditions for extend periods can adversely affect the long-term reliability of the device. Other conditions 1) Do not use or store modules in the corrosive atmosphere, especially where chloride gas, sulfide gas, acid, alkali, salt or the like are contained. Also, avoid exposure to moisture. 2) Store the modules where the temperature and relative humidity do not exceed 5 to 40 and 20 to 60%. 3) Assemble the modules within 6 months. Check the soldering ability in case of 6 months over. 2014 LGIT. All rights reserved. REG. DATE : 2014.04.08 S P E C I F I C A T I O N REV.
