Notes

Inductance tested at 10 kHz, 0.1 Vrms, 0 Adc using an Agilent/HP 4132 impedance analyzer or equivalent
DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator
Isat: DC current at 25°C that causes a 10% (typ) inductance drop from its value without current. Temperature derating curves.
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. Temperature derating curves.

Termination:

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