Fault Current (Amps)
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.

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.
