1 When ordering, please specify tolerance, termination and packaging codes: e.g. 1812CS-333XGLC
Tolerance: G = 2%, J = 5% (Table above shows stock tolerances in bold.)
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
E = Halogen free component. RoHS compliant silver-palladium-platinum-glass frit terminations.
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 using a Coilcraft SMD-A fixture in an Agilent/HP 4286A impedance analyzer with Coilcraft-provided correlation pieces.
3 Tolerances in bold are stocked for immediate shipment.
4 Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
5 SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
6 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.
7 Irms: Current that causes a 15°C temperature rise from 25°C ambient. Details
8 Ambient temperature range: –40°C to +125°C with Irms current.
+125°C to +140°C with derated current. Derating curve
9 Storage temperature range: Component: –40°C to +140°C
Tape and reel packaging: –40°C to +80°C
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 with pure water or alcohol only. Other solvents.
