If you’re designing with EMC in mind, please note that all of Murata Power
Solutions' 3.6-10 Watt UNR Series 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. Correlation to other specifi cations
can be supplied upon request. Radiated emissions plots to FCC and CISPR 22
for model UNR-3.3/3-D5SM appear below.
