Notes:
•
•
•
•
MF-MSMF models cannot be wave soldered. Please contact Bourns for
hand soldering recommendations.
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.
