Moisture Sensitivity of µModule Devices µModule Package Technology The Moisture Sensitivity Level (MSL) of µModule packages is unique to each µModule device. Factors such as construction and component layout influence the MSL performance. µModule packages are rated MSL 3 or lower, with floor life and maximum allowed peak body temperatures specified by J-STD-020. For more information, please see Module Design and Manufacturing Resources: http://www.linear.com/designtools/packaging/umodule.php MSL 3 All LGA (package code V) and BGA (package code Y) packages except for devices rated MSL 4 in list below.
