performance in specific
customer applications may
differ from these values due
to the influence of other
variables.
Specifications are subject to change without notice.
Customers should verify actual device performance in their specific applications.

Solder Reflow Recommendations
Notes:
MF-SMDF 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.
