If you’re designing with EMC in mind, please note that all of DATEL’s
A-Series UWR 6-10 Watt DC/DC Converters have been characterized for
radiated and conducted emissions in our new EMI/EMC laboratory. 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 emissions plots to
FCC and CISPR 22 for model UWR-12/665-D5A appear below.
Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For DATEL A-Series
UWR 6-10 Watt DC/DC Converters, you should use slow-blow type fuses
with values no greater than the following:

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.
DATEL’s world-class design, development and manufacturing team stands
ready to work with you to deliver the exact power converter you need for
your demanding, large volume, OEM applications. And ... we’ll do it on
time and within budget!
Our experienced applications and design staffs; quick-turn prototype
capability; highly automated, SMT assembly facilities; and in-line SPC
quality-control techniques combine to give us the unique ability to design
and deliver any quantity of power converters to the highest standards of
quality and reliability.
We have compiled a large library of DC/DC designs that are currently used
in a variety of telecom, medical, computer, railway, aerospace and indus-
trial applications. We may already have the converter you need.

effective power converters available.
Quality and Reliability
The A-Series are the first DC/DC Converters to emerge from DATEL’s 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
2. To design with safety margins by adhering to a strict set of derating
3. To locate potential design weaknesses early in the product-development
4. To prove that early design improvements are effective by employing a
