The output range is limited by Vin. (Vin x 0.8) Vout. Use adequate ground plane and copper thickness adjacent to the converter.
All speci cations are at nominal line voltage, Vout=nominal (5V for W12 models) and full load,
Ripple and Noise (R/N) and no-load input current are shown at Vout=1V. See specs for details.
+25 deg.C. unless otherwise noted.
Output capacitors are 10 F ceramic. Input cap is 22 F. See detailed speci cations.
I/O caps are necessary for our test equipment and may not be needed for your application.

Product Label
Because of the small size of these products, the product label contains a
Model Number Product Code
character-reduced code to indicate the model number and manufacturing date
OKL-T/1-W12P-C L01101
code. Not all items on the label are always used. Please note that the label
OKL-T/1-W12N-C L00101
differs from the product photograph. Here is the layout of the label:
The manufacturing date code is four characters:
XXXXXX Product code
Mfg.
First character Last digit of manufacturing year, example 2009
date YMDX Rev. Revision level
code
Second character Month code (1 through 9 = Jan-Sep;
O, N, D = Oct, Nov, Dec)
Figure 2. Label Artwork Layout
Third character Day code (1 through 9 = 1 to 9, 10 = 0 and
11 through 31 = A through Z)
The label contains three rows of information:
Fourth character Manufacturing information
First row Murata Corporation mark
Second row Model number product code (see table)
Third row Manufacturing date code and revision level
