1. Inductance is for the primary, measured at 40 kHz, 0.1 Vrms, 0 Adc.
2. Peak primary current drawn at minimum input voltage.
3. DC current that causes an inductance drop of 30% (typ) from its value
without current.
4. Leakage inductance is for the primary winding with all other windings
shorted.
5. 4700 Vrms, isolation (hipot) measured between Pri/Aux and Sec windings for one minute.
6. 16 V, 1.25 A is for the Sec winding; 20 V, 35 mA is for the Aux winding.
7. The insulation class may be Functional, Basic, or Reinforced, dependingon the application variables such as working voltage, pollution degree,OVC, and Altitude. Please contact us for full details.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
