Notes

Inductance tested at 1 kHz, 1 Vrms, and it is measured on Agilent/HP 4263B LCR meter or equivalent.
DCR is per winding measured at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
Interwinding isolation (hipot) tested for one minute.

Termination:

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