What is the Moisture Sensitivity Level (MSL)of my RF module
Panasonic wireless modules are classified as MSL 3, Moisture Sensitivity Level, devices, independent of whether the module’s components have a lower MSL classification.
This classification means all products must be packed in MSL 3 vacuum bags with silica gel.
This rigorous MSL3 classification insures that the module’s PCB will not be exposed to excessive moisture.
Manufacturers may, after determining that all active components of the module have a lower MSL rating, independently downgrade the MSL handling procedures at the manufacturer’s own risk. Panasonic assumes no risk nor liability for storing or handling products outside of the specifications defined in in the data sheet of the product.
