注释

Output is for the secondary. Bias winding output is 18 V, 20 mA.
Inductance is for the primary (pins 1 – 3), measured at 250 kHz, 0.3 Vrms.
Leakage inductance is for the primary winding (pins 1 – 3) with the secondary winding shorted.
1500 Vrms, one minuteisolation, primary and bias windings to secondary winding
