1. When ordering, specify tolerance, termination and packaging codes:

Core material Ceramic

1008HQ-R10XGRC
F = 1% G = 2% J = 5%
(Table shows stock tolerances in bold.)
Termination: R = RoHS compliant matte tin over nickel over silverplatinum-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 thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
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 partnumbering system, Coilcraft is eliminating theneed for multiple packaging codes. When ordering,
simply change the last letter of your part number
from B to C.
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 testfixture.
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 aCoilcraft SMD­‑D test fixture.
7. DCR measured on a Cambridge Technology micro-ohmmeter and aCoilcraft 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.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Terminations RoHS compliant matte tin over nickel over silver
platinum-glass frit. Other terminations available at additional cost.
