Notes

Inductance is for the primary, measured at 300 kHz, 0.1 Vrms, 0 Adc.
Minimum inductance is for the primary, measured at 300 KHz, 0.1 Vrms, 3 Adc.
Leakage Inductance is for the primary, measured with secondary windings shorted together.
1500 Vrms, one minute isolation (hipot) between primary to secondary.
