메모

Inductance is measured at 150 kHz, 0.1 Vrms.
DC current at which the inductance drops 10% (typical) from its value without current.
DCR is with the secondary windings connected in parallel.
Leakage inductance is for the three windings of the primary with the secondary windings shorted.
Turns ratios are with the primary and secondary windings connected in parallel.
3000 Vrms, one minute primary to secondary isolation.
