8.1. Storage Conditions
The calculated shelf life in a sealed bag is 12 months if stored between 0°C and 70˚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 in 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℃ for 8hrs.
