➀ Please refer to the part number structure for additional ordering information and options.

➁ All specifications are at nominal line voltage and full load, +25 deg.C. unless otherwise noted.

See detailed specifications. Output capacitors are 1 μF ceramic in parallel with 10 μF electrolytic

with no input caps.These caps are necessary for our test equipment and may not be needed for

your application.

➂ Minimum efficiency applies over all input voltages, the full operating temperature range and full

load.
