Document 190-1 Chip Inductors– 1008HQ Series (2520) • Highest Q factors of any Coilcraft chip this body size, roughly 20% higher than our popular 1008CS and HS parts. • Exceptional SRFs, tight tolerance and batch consistency Part number1 1008HQ-3N0X_L_2 1008HQ-4N1X_L_ 1008HQ-7N8X_L_2 1008HQ-10NX_L_ 1008HQ-12NX_L_ 1008HQ-18NX_L_ 1008HQ-22NX_L_ 1008HQ-33NX_L_ 1008HQ-36NX_L_ 1008HQ-39NX_L_ 1008HQ-47NX_L_ 1008HQ-56NX_L_ 1008HQ-68NX_L_ 1008HQ-82NX_L_ 1008HQ-R10X_L_ Inductance3 (nH) 3.0 @ 50 MHz 4.1 @ 50 MHz 7.8 @ 50 MHz 10 @ 50 MHz 12 @ 50 MHz 18 @ 50 MHz 22 @ 50 MHz 33 @ 50 MHz 36 @ 50 MHz 39 @ 50 MHz 47 @ 50 MHz 56 @ 50 MHz 68 @ 50 MHz 82 @ 50 MHz 100 @ 50 MHz Percent tolerance4 5 5 5 5,2 5,2 5,2,1 5,2 5,2 5,2 5,2 5,2,1 5,2,1 5,2,1 5,2 5,2 1. 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. Electrical specifications at 25°C. 9. Temperature coefficient of inductance: +25 to +125 ppm/°C. See Color Coding section for part marking data. Refer to Doc 362 “Soldering Surface Mount Components” before soldering. Coilcraft Designer’s Kit C323 contains samples of all 5% inductance tolerance parts. Kits with 2% tolerance are also available.
