Please refer to the part number structure for additonal ordering model numbers and options.
 All specifi cations are typical at nominal line voltage, nominal output voltage and full load, +25°C
unless otherwise noted. See detailed specifi cations.
 External capacitors used for testing: with appropriate voltage and current ratings, output
capacitors are 1 µF in parallel with 10 µF. Input cap is 33 µF. All caps are low ESR types. Contact
Murata Power Solutions for details.
 I/O caps are necessary for our test equipment. The values and number of capacitors may be
modifi ed depending on the application.
