Notes:

1. All electrical specifications are referenced to 25°C ± 5°C ambient.
2. The inductance is for the primary, measured at 250 kHz, 0.5 Vrms, 0 ADC.
3. The leakage inductance is for the primary with the secondary and aux windings shorted.
4. Isat, saturation current, means DC current at 25°C that causes an initial inductance drop of 15% approx.
5. Output is for the secondary. Output of the aux winding is 12 V, 30 mA.
