注释

Inductance is measured at 50 kHz, 0.1 Vrms.
DCR for the primary is with the windings connected in parallel.
Leakage inductance is for the primary with windings connected in parallel and with the secondary winding shorted.
Turns ratios are with the primary windings connected in parallel.
1500 Vrms, one minute interwinding isolation
