1 When ordering, please specify tolerance, termination and packaging codes: e.g. 1008HQ-R10XGLC
Tolerance: F = 1%, G = 2%, J = 5% (Table above shows stock tolerances in bold.)
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 (2000 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 (7500 parts per full reel).
2 Part is wound on a low profile coilform.
3 Inductance measured at 50 MHz using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
4 Tolerances in bold are stocked for immediate shipment.
5 Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
6 For SRF >6 GHz, measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD-D test fixture.  For SRF <6 GHz, measured using  an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
7 DCR measured at 25°C on a Cambridge Technology Micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
8 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.
9 Ambient temperature range: −40°C to +125°C with Irms current.
10 Storage temperature range: Component: −40°C to +140°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +140°C (Ambient + temperature rise)
12 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.
13 Electrical specifications at 25°C.
14 Temperature coefficient of inductance (TCL): +25 to +125 ppm/°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested with pure water or alcohol only. Other solvents.
