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
