c These are partial model numbers. Please refer to the full model number structure for complete
ordering part numbers.
d Sense input is not included for 12 VOUT and higher models. Sense is optional for 5 VOUT and lower.
e All specifications are typical at nominal line voltage and full load, +25 deg.C. unless otherwise
noted. See detailed specifications.
f Output capacitors are 1 μF ceramic || 10 μF electrolytic. Input cap is 22 μF, low ESR.
g I/O caps are necessary for our test equipment and may not be needed for your application.

Soldering Guidelines
Murata Power Solutions recommends the specifications below when installing these converters. These specifications vary depending on the solder type. Exceeding these specifica-
tions may cause damage to the product. Be cautious when there is high atmospheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your production
environment may differ; therefore please thoroughly review these guidelines with your process engineers.
