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 TWR 12-15 Watt DC-DC Converters, you should use
slow-blow type fuses with values no greater than 2A.

EMI RADIATED EMISSIONS
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 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. Correlation to
other speci?cations can be supplied upon request. Radiated emissions
plots to FCC and CISPR 22 for model TWR-5/1500-15/250-D48A appear
below. Published EMC test reports are available for each model number.

? Quality and Reliability
The A-Series are the ?rst DC-DC Converters to emerge from Murata Power
Solutions’ new, company-wide approach to designing and manufacturing
the most reliable power converters available. The ?ve-pronged program
draws our Quality Assurance function into all aspects of new-product
design, development, characterization, quali?cation 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 quali?cation 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
