Notes

Inductance shown for each winding, measured at 10 kHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4263B LCR meter or equivalent.
Leakage inductance is measured from pin 1 to pin 2 with pins 4 and 3 shorted.
Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
DCR is for each winding.
2000 Vrms, one minute isolation (hipot) between windings.

Termination:

L = RoHS compliant tin-silver (96.5/3.5) over copper
T = RoHS tin-silver-copper (95.5/4/0.5). (Special order, added cost)
S = non-RoHS tin-lead (63/37). (Special order, added cost)
