UWR Series
Single Output, High Reliability, 2" x 1", 6-10 Watt, DC-DC Converters
Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For Murata Power
Solutions A-Series UWR 6-10 Watt DC/DC Converters, you should use slow-
blow type fuses with values no greater than the following:
VIN Range
D5A
D12A and D24E
D48A and D48E
Fuse Value
3A
2A
1A
EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of Murata Power
Solutions' A-Series UWR 6-10 Watt DC/DC Converters have been character-
ized for radiated and conducted emissions in our new EMI/EMC labora-
tory. Testing is conducted in an EMCO 5305 GTEM test cell utilizing EMCO
automated EMC test software. Radiated emissions are tested to the limits
of FCC Part 15, Class B and CISPR 22 (EN 55022), Class B. Radiated emis-
sions plots to FCC and CISPR 22 for model UWR-12/665-D5A appear below.

effective power converters available.
Quality and Reliability
The A-Series are the first DC/DC Converters to emerge from Murata Power
Solutions' new, company-wide approach to designing and manufacturing
the most reliable power converters available. The five-pronged program
draws our Quality Assurance function into all aspects of new-product
design, development, characterization, qualification and manufacturing.
Design for Reliability
Design for Reliability is woven throughout our multi-phased, new-product-
development process. Design-for-reliability practices are fully documented
and begin early in the new-product development cycle with the following
goals:
1. To work from an approved components/vendors list ensuring the use of
reliable components and the rigorous qualification of new components.
2. To design with safety margins by adhering to a strict set of derating
guidelines and performing theoretical worst-case analyses.
3. To locate potential design weaknesses early in the product-development
cycle by using extensive HALT (Highly Accelerated Life Testing).
4. To prove that early design improvements are effective by employing a
thorough FRACA (Failure Reporting Analysis and Corrective Action) System.
Soldering Guidelines
Murata Power Solutions recommends the specifications below when installing these
converters. These specifications vary depending on the solder type. Exceeding these
specifications may cause damage to the product. Be cautious when there is high atmo-
spheric humidity. We strongly recommend a mild pre-bake (100° C. for 30 minutes). Your
production environment may differ; therefore please thoroughly review these guidelines
with your process engineers.
