Chip Inductors
–
1008HQ (2520)
• Highest Q factors of any Coilcraft chip this body size, roughly
20% higher than our popular 1008CS and HS parts.
Coilcraft Designer’s Kit C323 contains samples of all
5% inductance tolerance parts. Kits with 2% tolerance
are also available.To order, contact Coilcraft or purchase
on-line at http://order.coilcraft.com.
• Exceptional SRFs, tight tolerance and batch consistency

1. When ordering, specify tolerance, termination and packaging codes:
1008HQ-R10XGLC
Core material Ceramic
Terminations RoHS compliant silver-palladium-platinum-glass frit.
Other terminations available at additional cost.
Tolerance:
F = 1% G = 2% J = 5%
Weight 32.4– 35.7 mg; 17.1– 17.7 mg (Low profile parts)
(Table shows stock tolerances in bold.)
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
Ambient temperature –40°C to +125°C with Irms current, +125°C
Special order: T = RoHS tin-silver-copper
to +140°C with derated current
(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).
Storage temperature Component: –40°C to +140°C.
Tape and reel packaging: –40°C to +80°C
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.
Resistance to soldering heat Max three 40 second reflows at
+260°C, parts cooled to room temperature between cycles
D = 13″ machine-ready reel. EIA-481 embossed plastic
tape Factory order only, not stocked (7500 parts
per full reel).
Temperature Coefficient of Inductance (TCL) +25 to +125 ppm/°C
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
2. Part is wound on low profile coilform.
Failures in Time (FIT) / Mean Time Between Failures (MTBF)
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.
One per billion hours / one billion hours, calculated per Telcordia SR-332
Packaging 2000/7″ reel; 7500/13″ reel

4 mm pocket spacing, 1.6 mm pocket depth
PCB washing Tested with pure water or alcohol only. For other solvents,
see Doc787_PCB_Washing.pdf.
7. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
