Notes

Inductance is for the primary, measured at 300 kHz, 0.1 Vrms, 0 Adc.
DC current that causes the primary inductance drop 30% from its value without current.
Leakage inductance is for the primary and is measured with the secondary shorted.
3000 Vrms, one minute isolation (hipot) between primary and secondary.
