Package Handling Procedures

•

Moisture Classification Level: Level 3

•

Storage: Parts may be stored in unopened vacuum-packed antistatic bag up to a minimum 
of 12 months at < 40°C and 90% humidity.  Parts may be stored outside of bag indefinitely 
at 20% humidity.

•

Floor Life: Packages will absorb moisture after opening the bag.  Parts must be mounted on 
PCB within 48 hours after bag is opened; otherwise, baking is required.  Floor life 
conditions are 30°C and 60% humidity.
