1 When ordering, please specify packaging code: e.g. NA5936-ALD
  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.
2 Inductance tested at 50 MHz on an Agilent/HP 4191A Impedance Analyzer or equivalent with a Coilcraft SMD-A fixture using Coilcraft supplied correlation.
3 Q tested at 50 MHz on an Agilent/HP 4291A Impedance Analyzer or equivalent with a Coilcraft SMD-D fixture using Coilcraft supplied correlation.
4 SRF tested with an Agilent/HP 8753D network analyzer and a Coilcraft CCF1248 test fixture. Details
5 DCR tested at 25°C on a Keithley 580 Micro-ohmmeter. For other operating temperatures,use this DCR at Temperature calculator.
6 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.
7 Ambient temperature range: −40°C to +125°C with Irms current.
8 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
9 Maximum part temperature: +140°C (Ambient + temperature rise)
10 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
11 Electrical specifications at 25°C.
12 Temperature coefficient of inductance: +5 to +70 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
