3.7 Storage Conditions
The calculated shelf life in a sealed bag is 12 months if stored between 0 °C and 40 °C at less than 90% relative
humidity (RH). After the bag is opened, devices that are subjected to solder reflow or other high temperature
processes must be handled in the following manner:
Mounted within 168 hours of factory conditions, i.e. < 30 °C at 60% RH.
Storage humidity needs to maintained at < 10% RH.
Baking is necessary if the customer exposes the component to air for over 168 hrs, baking conditions: 125
°C for 8 hrs.
