•
MF-NSML models cannot be wave soldered or hand soldered. Please
contact Bourns for 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.
Excess solder may cause a short circuit, especially during hand soldering.
Please refer to the Multifuse
