3 General Safety Precautions and Usage Considerations

Storage

3.2.1

General 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.

3.2.2

Moisture-proof packing

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.

(1) General precautions

Follow the instructions printed on the device cartons regarding transportation and storage.

• 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.
