MF-USMF models cannot be wave soldered.
If refl ow temperatures exceed the recommended profi le,
devices may not meet the performance requirements.
Compatible with Pb and Pb-free solder refl ow profi les.
Excess solder may cause a short circuit, especially during hand
soldering. Please refer to the Multifuse
Recommendation guidelines.
