2. Inductance is for the primary, measured at 10 kHz, 0.1 Vrms, 0 Adc.
3.Ipk is peak primary current drawn at minimum input voltage.
4. Leakage inductance measured between pins 1 and 3 with pins 4 and 6
shorted.
5. Operating temperature range –40°C to +85°C.
6. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
