注释

Output is for the secondary winding. Output of the bias winding output is 12 V, 20 mA.
Inductance is measured at 150 kHz, 0.1 Vrms.
Peak primary current drawn at minimum input voltage
DCR for the primary is with the windings connected in parallel.
Leakage inductance is for the primary windings connected in parallel and with the secondary winding shorted.
Turns ratios are with the primary windings connected in parallel.
1500 Vrms, one minute isolation from primary to secondary windings.

端子:

RoHS-compliant. 260°C compatible. Tin-silver over tin over nickel over phos bronze terminations. Other terminations available at additional cost.
