➀ Please refer to the part number structure for additional options and complete
ordering part numbers.
➁ All specifi cations are typical at nominal line voltage and full load, +25 deg.C. unless
otherwise noted. See detailed specifi cations.
➂ Minimum output load for all models is 10% of maximum current.
➃ RoHS-6 compliance does not claim EU RoHS exemption 7b (lead in solder).
