Notes

When ordering, please specify packaging code: e.g. NA5936-ALD
Inductance tested at 50 MHz on an Agilent/HP 4191A Impedance Analyzer or equivalent with a Coilcraft SMD-A fixture using Coilcraft supplied correlation.
Q tested at 50 MHz on an Agilent/HP 4291A Impedance Analyzer or equivalent with a Coilcraft SMD-D fixture using Coilcraft supplied correlation.
SRF tested with an Agilent/HP 8753D network analyzer and a Coilcraft CCF1248 test fixture. Details
DCR tested at 25°C on a Keithley 580 Micro-ohmmeter. For other operating temperatures,use this DCR at Temperature calculator.
Irms: Current that causes a 15°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings.

Termination:

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

Packaging:

D = 13″ machine-ready reel. EIA-481 embossed plastic tape (800 parts per full reel).
B = Less than full reel. In tape, but not machine-ready. To have a leader and trailer added ($25 charge), use code letter D instead.

Environmental
