7.3. Humidity Sensitivity (MSL)
The SLM500 module meets moisture sensitivity level 3. The dry package is subjected to
the J-STD-020C specification in accordance with the IPC/JEDEC standard under ambient
conditions of temperature <30 degrees and relative humidity <60%. Under ambient
conditions of temperature <40 degrees and relative humidity <90%, the shelf life is at least 6
months without unpacking. After unpacking, Table 22 lists the shelf life of the modules for
different moisture sensitivity levels.
