1 When ordering, please specify termination and packaging codes: e.g. HA4031-ALC
  Termination: L = RoHS compliant silver-palladium-platinum-glass frit
Special order, added cost: T = RoHS tin-silver-copper (95.5/4/0.5) or
S
= non-RoHS tin-lead (63/37).
Packaging: C = 7" machine-ready reel
EIA-481 embossed plastic tape (600 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 C instead.
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
2 Inductance measured at 50 MHz, using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
3 Q measured at 50 MHz, using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
4 SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
5 DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter and a Coilcraft CCF859 test fixture. 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 (TCL): +25 to +125 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
