1. When ordering, specify tolerance, termination and packaging codes:
1812SMS-R12GLC
Tolerance: G = 2% J = 5%
Termination: L = RoHS compliant tin-silver (96.5/3.5) over copper.
Special order: 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, 500 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 machine-ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked, 2000 parts per
full reel.
2. Inductance tested at 150 MHz on an Agilent/HP 4286A LCR meter or
equivalent with a Coilcraft SMD-A test fixture and correlation.
3. Tolerances in bold are stocked for immediate shipment.
4. Q tested at 150 MHz on an Agilent/HP 4291A Impedance Analyzer with
an Agilent/HP 16193 test fixture or equivalents.
5. SRF tested on the Agilent/HP 8753D Network Analyzer or equivalent
and a Coilcraft CCF1248 test fixture.
6. DCR tested on the Cambridge Technology Model 510 Micro-ohmmeter
or equivalent.
7. 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.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Storage temperature Component: –40°C to +140°C.
Tape and reel packaging: –40°C to +80°C
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
Temperature Coefficient of Inductance (TCL) +5 to +70 ppm/°C
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 500/7 reel; 2000/13 reel Plastic tape: 12 mm wide,
0.3 mm thick, 8 mm pocket spacing, 4.33 mm pocket depth
Recommended pick and place nozzle: OD: 0.110; ID: 0.091
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
Air core inductors feature high Q and current handling
Acrylic top provides a flat surface for pick and place
Solder coated leads ensure reliable soldering
