Please observe the limits below for voltage input and output ranges. These
limits apply at all output currents.
Soldering Guidelines
Murata Power Solutions recommends the specifi cations below when installing 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.
