Chip Inductors– 1008HQ (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

tolerance4
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. 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.
9. Electrical specifications at 25°C.
