•
MF-USMF 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.
Excess solder may cause a short circuit, especially during hand
soldering. Please refer to the Multifuse
