When ordering, specify tolerance, termination and packaging codes: 1008HQ-R10XGLC Tolerance: F=1% G = 2% J = 5% (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. Part is wound on low profile coilform. 3. Inductance measured 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 less than 6 GHz, measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. For SRF greater than 6 GHz, measured using an Agilent/HP 8722ES network analyzer and a Coilcraft SMD‑D test fixture. 7. DCR measured on a Cambridge Technology micro-ohmmeter and a Coilcraft CCF840 test fixture. 8. Current that causes a 15°C temperature rise from 25°C ambient.
