Notes

Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using an Agilent/ HP 4263B impedance analyzer or equivalent.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Leakage inductance is for the primary and is measured with the secondary shorted.
Isolation: 3000 Vrms, one minute Pri and P1 to S1 and Sense; 1500 Vrms all windings to core

Termination:

RoHS-compliant. Tin-silver (96.5/3.5) over tin over copper terminations.
