PART NUMBER STRUCTURE
‡
Some model number combinations may not
be available. See website or contact your local
Murata sales representative.
*Minimum order quantity is required.
Samples available with standard pin
length only.
➀ Please refer to the part number structure for additional options and complete
ordering part numbers.
➁ The minimum output load for the BEI-15W series is 10% of maximum current to
meet published specifications. The converter will not be damaged by less than
10% load but some specs may degrade slightly.
➂ All specifications are at nominal line voltage and full load, +25 °C. unless other-
wise noted. See detailed specifications and notes for full conditions.
Output capacitors are 1 μF ceramic in parallel with 10 μF electrolytic. The input cap
is 100 μF, low ESR.
I/O caps are necessary for our test equipment and may not be needed for your
application.
➃ RoHS-6 compliance does not claim EU RoHS exemption 7b (lead in solder).
➄ Balanced loads, 10% to 100% loads.
