Solder Reflow Recommendations

Notes:

•

MF-MSMF 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

recommendation guidelines.
