Absolute Maximum Ratings
Storage Considerations
These are stress ratings only and functional operation of
the device at these ratings or any other above those
indicated in the operation sections of the specifications is
not implied. Exposure to absolute maximum rating condi-
tions for extended periods of time may affect reliability.
Storage in a low humidity environment is preferred. Large
high density plastic packages are moisture sensitive and
should be stored in Dry Vapor Barrier Bags. Prior to usage,
the parts should remain bagged and stored below 40°C
and 60%RH. If the parts are removed from the bag, they
should be used within 48 hours or stored in an environ-
ment at or below 20%RH. If the above conditions cannot
be followed, the parts should be baked for four hours at
125°C in order remove moisture prior to soldering. Zywyn
ships product in Dry Vapor Barrier Bags with a humidity
indicator card and desiccant pack. The humidity indicator
should be below 30%RH.
