Solder Reflow Recommendations
Notes:
•MF-MSMF models cannot be wave soldered.
•If reflow temperatures exceed the recommended profile, devices may not meet the performance
requirements.
• Compatible with Pb and Pb-free solder reflow profiles.
The Time to Trip curves represent typical performance of a device in a simulated application
environment. Actual performance in specific customer applications may differ from these values due
to the influence of other variables.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.
