Please refer to the Part Number Structure when ordering.
These specifications are preliminary. Contact Murata Power Solutions for availability.
All specifications are at nominal line voltage and full load, +25°C unless otherwise noted. See
detailed specifications. Output capacitors are 1 μF ceramic multilayer in parallel with 10 μF
electrolytic.
I/O caps are necessary for our test equipment and may not be needed for your application.
➃ Regulation specifications describe output voltage deviations from a nominal/midpoint value to either
extreme (50% load step).

Product Label
As shown in figure 2, because of the small size of these products, the product labels
contain a simplified Murata-PS logo and a character-reduced code to indicate the model
