Datasheet

PART NUMBER STRUCTURE
➀ Dimensions are in inches (mm).
➁ These are partial model numbers. Please refer to the part number structure for complete ordering part numbers.
➂ All specifications are at nominal line voltage, Vout=nominal (5V for W40 models) and full load, +25 ˚C. unless
otherwise noted.
Output capacitors are 1 µF ceramic and 10 µF electrolytic in parallel. Input cap is 22 µF. See detailed specifications.
I/O caps are necessary for our test equipment and may not be needed for your application.
➃ Ripple/Noise is shown at Vout = 1V.
➄ No load input current is shown at Vout = 0.75V.
➅ For Vout = 1V, Vin ≤ 32V. For Vout = 0.75V, Vin ≤ 24V.

Product Label
Because of the small size of these products, the product label contains 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 dif-
fers from the product photograph on page 1. Here is the layout of the label:
The label contains three rows of information:
First row – Murata Power Solutions logo
Second row – Model number product code (see table)
Third row – Manufacturing date code and revision level
The manufacturing date code is four characters:
First character – Last digit of manufacturing year, example 2009
Second character – Month code (1 through 9 and O through D)
Third character – Day code (1 through 9 = 1 to 9, 10 = O and
11 through 31 = A through Z)
Fourth character – Manufacturing information
