Output Current (Note 7)
Current-limited. Devices can withstand a
sustained short circuit without damage.
The outputs are not intended to accept
appreciable reverse current.

Lead Temperature
See soldering specifications
Absolute maximums are stress ratings. Exposure of devices to greater than any of
any of these conditions may adversely affect long-term reliability. Proper operation
under conditions other than those listed in the Performance/Functional Specifications
Table is not implied or recommended.
Specification Notes:
(1) Specifications are typical at +25 °C, Vin=nominal (+12V.), Vout=nominal (+5V), full load, external caps and
natural convection unless otherwise indicated. Extended tests at full power must supply substantial forced
airflow.
All models are tested and specified with external 1 μF paralleled with 10μF 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.
(2) 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.
(3) 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.
(4a) Mean Time Before Failure is calculated using the Telcordia (Belcore) SR-332 Method 1, Case 3, ground fixed
conditions, Tpcboard=+25 ˚C, full output load, natural air convection.
(4b) Mean Time Before Failure is calculated using the MIL-HDBK-217N2 method, ground benign, +25ºC., full
output load, natural convection.
