Notes:

• MF-NSMF 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.
