Please refer to the Part Number Structure when ordering.

All specifi cations are typical at nominal line voltage and full load, +25°C unless otherwise noted.
See detailed specifi cations. Output capacitors are 1 F ceramic multilayer in parallel with 10 F and a
220uF/100V external input capacitor is needed for the ULS-12/8.3-D48 model.
I/O caps are necessary for our test equipment and may not be needed for your application.

Regulation specifi cations describe output voltage deviations from a nominal/midpoint value to either
extreme (50% load step).

Product Label
As shown in fi gure 2, because of the small size of these products, the product
labels contain a simplifi ed Murata-PS logo and a character-reduced code to
indicate the model number and manufacturing date code. Not all items on
the label are always used. Please note that the label differs from the product
