Datasheet

➀ Please refer to the part number structure for additional ordering information and options.
➁ All specifi cations are typical at nominal line voltage and full load, +25°C unless otherwise noted. See
detailed specifi cations. Output capacitors are 1 µF || 10 µF. These caps are necessary for our test equip-
ment and may not be needed for your application.
