Moisture-proof packing should be handled with care. The handling procedure
specified for each packing type should be followed scrupulously. If the proper
procedures are not followed, the quality and reliability of devices may be degraded.
This section describes general precautions for handling moisture-proof packing. Since
the details may differ from device to device, refer also to the relevant individual
datasheets or databook.

Storage
Avoid storage locations where devices will be exposed to moisture or direct sunlight.
Follow the instructions printed on the device cartons regarding
transportation and storage.
The storage area temperature should be kept within a temperature range
of 5°C to 35°C, and relative humidity should be maintained at between
45% and 75%.
Do not store devices in the presence of harmful (especially corrosive)
gases, or in dusty conditions.
Use storage areas where there is minimal temperature fluctuation. Rapid temperature changes can cause
moisture to form on stored devices, resulting in lead oxidation or corrosion. As a result, the solderability of
the leads will be degraded.
When repacking devices, use anti-static containers.
Do not allow external forces or loads to be applied to devices while they are in storage.
If devices have been stored for more than two years, their electrical characteristics should be tested and their
leads should be tested for ease of soldering before they are used.
Do not drop or toss device packing. The laminated aluminum material in it can be rendered ineffective by
rough handling.
The storage area temperature should be kept within a temperature range of 5°C to 30°C, and relative humidity
should be maintained at 90% (max). Use devices within 12 months of the date marked on the package seal.
