Notes

Output of the auxiliary winding is 10.2 V.
Inductance is for the primary, measured at 150 kHz, 0.1 Vrms, 0 Adc
DCR for primary is per both windings connected in parallel, measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary winding with the secondary windings shorted.
Turns ratio is with the primary windings connected in parallel.
1500 Vrms, one minute isolation (hipot) from pri and aux to sec.
500 Vrms, one minute isolation (hipot) from pri to aux.
