tifi cations and to avoid injury to personnel or equipment, the user must supply an
external fast-blow fuse to the input terminals. See fuse information.
ceramic/tantalum output capacitors and a 100μF external input capacitor. Q48
models test with a 35μF input cap. All capacitors are low ESR types. Contact Murata
Power Solutions for details. These capacitors are necessary to accommodate our
test equipment and may not be required to achieve specifi ed performance in your
applications. However, Murata Power Solutions recommends using these capacitors
in your application. All models are stable and regulate within spec under no-load
conditions.
All specifi cations are typical unless noted. General conditions for Specifi cations are

tolerate brief full current outputs if the total RMS current over time does not exceed
the Derating curve. All Derating curves are presented at sea level altitude. Be aware
that power dissipation degrades as altitude increases.

slow transient response or degrade stability. Use only as much output fi ltering as
needed to achieve your noise requirements and no more. Thoroughly test your
system under full load with all components installed.
