| 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. | ||
