DRY PACKING
The reel is packed in an anti-humidity bag to protect
the devices from absorbing moisture during
transportation and storage.
FINAL PACKING
The sealed reel is packed into a cardboard box. A
secondary cardboard box is used for shipping
purposes.
RECOMMENDED METHOD OF STORAGE
Dry box storage is recommended as soon as the
aluminum bag has been opened to prevent moisture
absorption. The following conditions should be
observed, if dry boxes are not available:
• Storage temperature 10 °C to 30 °C
• Storage humidity ≤ 60 % RH max.
After more than 672 h under these conditions moisture
content will be too high for reflow soldering.
In case of moisture absorption, the devices will recover
to the former condition by drying under the following
condition:
192 h at 40 °C + 5 °C/- 0 °C and < 5 % RH
(dry air/nitrogen) or
96 h at 60 °C + 5 °C and < 5 % RH for all device
containers or
24 h at 100 °C + 5 °C not suitable for reel or tubes.
An EIA JEDEC standard JESD22-A112 level 2a label
is included on all dry bags.

ESD PRECAUTION
Proper storage and handling procedures should be
followed to prevent ESD damage to the devices
especially when they are removed from the antistatic
shielding bag. Electro-static sensitive devices warning
labels are on the packaging.
