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. Electrostatic

sensitive devices warning labels are on the packaging.
