4. Storage Test Conditions
Parameter Min Max Unit
Storage Temperature -10 +80
Storage Humidity(40℃)
Caution : The specifications in Table 1 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
-90 %
℃
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 is recommended where the temperature
and relative humidity 5 to 40℃ and 20 to 60%.
3) Assemble the modules within 6 months.
Check the soldering ability in case of 6 months over.
