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:
Core material Ceramic
Terminations RoHS compliant matte tin over nickel over silver
1008HQ-R10XGRC
platinum-glass frit. Other terminations available at additional cost.
Tolerance:
F = 1% G = 2% J = 5%
(Table shows stock tolerances in bold.)
Weight 32.4– 35.7 mg; 17.1– 17.7 mg (Low profile parts)
Ambient temperature –40°C to +125°C with Irms current
Maximum part temperature +140°C (ambient + temp rise).
Termination: R = RoHS compliant matte tin over nickel over silver-
platinum-glass frit.
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). Quantities less than
full reel available: in tape (not machine ready) or
with leader and trailer ($25 charge).
Storage temperature Component: –40°C to +140°C.
Tape and reel packaging: –40°C to +80°C
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).
B = Less than full reel. In an effort to simplify our part
numbering system, Coilcraft is eliminating the
need for multiple packaging codes. When ordering,
simply change the last letter of your part number
from B to C.
Temperature Coefficient of Inductance (TCL) +25 to +125 ppm/°C
Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /
85% relative humidity)
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
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.
PCB washing Tested to MIL-STD-202 Method 215 plus an additional
aqueous wash. See Doc787_PCB_Washing.pdf.
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.
