Through-hole Soldering Guidelines
Murata Power Solutions recommends the TH soldering specifi cations below when install-
ing these converters. These specifi cations vary depending on the solder type. Exceeding
these specifi cations may cause damage to the product. Your production environment may
differ; therefore please thoroughly review these guidelines with your process engineers.

SMT Refl ow Soldering Guidelines
The surface-mount refl ow solder profi le shown below is suitable for SAC305 type lead-
free solders. This graph should be used only as a guideline. Many other factors infl uence
the success of SMT refl ow soldering. Since your production environment may differ,
please thoroughly review these guidelines with your process engineers.
