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 8-11 Watt DC/DC Converters, you should use slow-blow
type fuses with values no greater than 3A.

power converters available.
EMI RADIATED EMISSIONS
If you’re designing with EMC in mind, please note that all of Murata Power
Solutions' TWR 8-11 Watt A-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 specifications can
be supplied upon request. Radiated emissions plots to FCC and CISPR 22 for
model TWR-5/1000-12/125-D5A appear below. Published EMC test reports are
available for each model number. Contact Murata Power Solutions' Applications
Engineering Department for more details.
