UWR Series
Single Output, High Reliability, 2" x 2", 14-20 Watt, DC/DC Converters
Typical Performance Curves (TA = +25°C)
The performance curves below were derived from actual test data for a
single model number (UWR-5/4000-D12A). Since all devices in the 14-20W
UWR A-Series have the same circuit topology, the performance curves are
representative of all devices.

EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of Murata Power
Solutions' UWR 14-20 Watt A-Series 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. Radiated emissions
plots to FCC and CISPR 22 for model UWR-5/4000-D12A appear below.
