Notes

Inductance is for the primary, measured on at 500 kHz, 0.2 Vrms, 0 Adc.
Isat: DC current that causes an inductance drop of 30% (typ) from its value without current.
Leakage Inductance is for the primary, measured with secondary windings shorted together.
3300 Vrms, one minute isolation (hipot) from primary to secondary.
