4. Electrical Specifications
4.1 Absolute Maximum Ratings
The absolute maximum ratings in Table 4-1 indicate levels where permanent damage to the device can
occur, even if these limits are exceeded for only a brief duration. Functional operation is not guaranteed under
these conditions. Operation at absolute maximum conditions for extended periods can adversely affect longterm reliability of the device.

4.2.1 Storage Condition
The calculated shelf life in 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:
a) Mounted within 168-hours of factory conditions < 30 °C /60%RH
b) Storage humidity needs to maintained at <10% RH
c) Baking is necessary if customer exposes the component to air over 168 hours, Baking condition:
125°C / 8hrs
