Specifications are typical at +25 deg.C, Vin=nominal (+12V. for D12 models), Vout=nominal (+5V for D12
models), full load, external caps and natural convection unless otherwise indicated. Extended tests at higher
power must supply substantial forced airflow.
All models are tested and specified with external 1 μF paralleled with 10 μF ceramic/tantalum output
capacitors and a 22 μF external input capacitor. All capacitors are low ESR types. These capacitors are
necessary to accommodate our test equipment and may not be required to achieve specified performance
in your applications. However, Murata Power Solutions recommends installation of these capacitors. All
models are stable and regulate within spec under no-load conditions.
Input Back Ripple Current is tested and specified over a 5 Hz to 20 MHz bandwidth. Input filtering is
Cin=2 x 100 μF tantalum, Cbus=1000 μF electrolytic, Lbus=1 μH.
Note that Maximum Power Derating curves indicate an average current at nominal input voltage. At higher
temperatures and/or lower airflow, the DC/DC converter will tolerate brief full current outputs if the total
RMS current over time does not exceed the Derating curve.
