Notes

Inductance is for each winding, measured at 200 kHz, 0.4 Vrms, 0 Adc.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for each primary, measured at 200 kHz, 0.4 Vrms with secondary pins shorted.
SRF is measured with the coils connected in series using an Agilent/HP 4192 or equivalent.
Isolation: 3000 Vrms primary to secondary; 500 Vrms windings to core.

Termination:

RoHS-compliant. Tin-silver over tin over copper terminations. Other terminations available at additional cost.
