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.
Coilcraft Designer’s Kit C323 contains samples of all 5%
inductancetoleranceparts. Kitswith2%tolerancearealso
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.
Special order: T = RoHS tin-silver-copper (95.5/4/0.5) or
S = non-RoHS tin-lead (63/37).
Ambient temperature –40°C to +125°C with Irms current, +125°C
to +140°C with derated current
Storage temperature Component: –40°C to +140°C.
Packaging: –40°C to +80°C
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.
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)
One per billion hours / one billion hours, calculated per Telcordia SR-332
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.
Packaging 2000/7″reel; 7500/13″ reel
Standard height parts: Plastic tape: 8 mm wide, 0.23 mm thick,
4 mm pocket spacing, 1.8 mm pocket depth
Low profile parts: Plastic tape: 8 mm wide, 0.3 mm thick,
4 mm pocket spacing, 1.6 mm pocket depth
PCB washing Only pure water or alcohol recommended
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.
