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.
Solder Reflow Recommendations
Preheating Soldering Cooling
Notes: * MF-NSMF models cannot be wave soldered. Please contact Bourns for hand soldering recommendations. * If reflow temperatures exceed the recommended profile, devices may not meet the performance requirements. * Compatible with Pb and Pb-free solder reflow profiles.
