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
differs from the product photograph. Here is the layout of the label:

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
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
Mean Time Before Failure (MTBF) Table
These figures use a standard MTBF probability calculation as an indication of component parts stress and life derating. The calculaton is based on separate MTBF
values for all internal parts in addition to stated environmental conditions. Two MTBF values are presented. The Telcordia method is widely used in industry, partic-
ularly telecom. The United States MIL-HDBK method is for military and industrial applications. Please refer to a qualified reliability engineer for more background.
