注释

Inductance is measured at 100 kHz, 0.1 Vrms.
DCR for the primary is with the windings connected in parallel.
Leakage inductance is for both windings of the primary with the secondary windings shorted.
Turns ratios are with the primary windings connected in parallel.
1500 Vrms, one minute isolation from primary to secondary windings.

端子:
