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
