➀ Dimensions are in inches (mm).
➁ Ripple and Noise is shown at Vout=1V. See specs for details.
➂ All specifications are at nominal line voltage, Vout= 5V and full load, +25 deg.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 equip-
ment and may not be needed for your application.
f Vin must be 2V or higher than Vout for 3.3 to 5V outputs.

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:

Figure 2. Label Artwork Layout
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
Model Number
OKR-T/3-W12-C
Product Code
R01103
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
