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.
Excess solder may cause a short circuit, especially during hand soldering.
