Notes

Inductance measured at 100 kHz, 0.1 V, 0 Adc using an Agilent/HP 4263B impedance analyzer or equivalent.
Isat: DC current at 25°C that causes the specified inductance drop from its value without current.
DCR measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
SRF tested on an Agilent/HP 4192A.
Irms: Current that causes the specified temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.
500 Vrms isolation winding to winding and from each winding to the core.

RoHS compliant tin-silver over tin over nickel over phos bronze. Other terminations available at additional cost.
