Input Fusing
Certain applications and/or safety agencies may require the installation of
fuses at the inputs of power conversion components. For Murata Power Solu-
tions A-Series TWR 12-15 Watt DC/DC Converters, you should use slow-blow
type fuses with values no greater than 2A.
Murata Power Solutions’ world-class design, development and manufactur-
ing 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 industrial
applications. We may already have the converter you need.
Contact us. Our goal is to provide you the highest-quality, most cost-effec-
tive power converters available.
If you’re designing with EMC in mind, please note that all of Murata Power
Solutions’ TWR A-Series 12-15 Watt DC/DC Converters have been charac-
terized for radiated and conducted emissions in our new EMI/EMC laboratory.
Testing is conducted in an EMCO 5305 GTEM test cell utilizing EMCO auto-
mated EMC test software. Radiated emissions are tested to the limits of FCC
Part 15, Class B and CISPR 22 (EN 55022), Class B. Correlation to other
specifications can be supplied upon request. Radiated emissions plots to
FCC and CISPR 22 for model TWR-5/1500-15/250-D48A appear below. Pub-
lished EMC test reports are available for each model number. Contact Murata
Power Solutions’ Applications Engineering Department for more details.

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 guide-
lines 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).
