1. When ordering, specify tolerance, termination and packaging codes:
1008AF-103XJLC Tolerance: J = 5% K = 10%
(Table shows stock tolerances in bold.) Termination: L = RoHS compliant silver-palladium-platinum-glass
frit. 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 (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″ machine-ready reel. EIA-481 embossed plastic tape. Factory order only, not stocked (7500 parts per full reel). 2. Inductance measured at 2.5 MHz using 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 at 2.5 MHz using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture. 5. SRF measured using an Agilent/HP 8753D network analyzer with a Coilcraft SMD-D fixture. 6. DCR measured on a Cambridge Technology Micro-ohmmeter. 7. DC current at 25°C that causes an inductance drop of 10% (typ) from its value without current. Click for temperature derating information. 8. Current that causes a 40°C temperature rise from 25°C ambient. This information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information. 9. Electrical specifications at 25°C. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. For part marking data, visit http://www.coilcraft.com/colrcode.cfm.
