Notes

Output of the secondary. Bias winding output is 12 V, 20 mA.
Inductance is for the primary, measured at 100 kHz, 0.1 Vrms, 0 Adc
DCR for the secondary is with windings connected in parallel. DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary, measured the secondary windings shorted.
3500 Vrms, one minute isolation, primary and bias to secondary winding.

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