Package and Handling Information 

Instructions on the shipping container label regarding exposure to 
moisture after the container seal is broken must be followed. 
Otherwise, problems related to moisture absorption may occur 
when the part is subjected to high temperatures during solder 
assembly. 

The SE2431L is rated to Moisture Sensitivity Level 1 (MSL1) at 
260 °C, and can be used for lead or lead-free soldering. For 
additional information, refer to the Skyworks Application Note, 
Solder Reflow Information, document number 200164. 

Care must be taken when attaching this product, whether it is 
done manually or in a production solder reflow environment. 
Production quantities of this product are shipped in a standard 
tape and reel format.
