1008CT (2520)
Document 102-1
Document 102-1 Revised 01/18/12
1. When ordering, specify tolerance, termination and packaging codes:
1008CT-101XJLC
Tolerance: F = 1% G = 2% J = 5%
(Table shows stock tolerances in bold.)
Termination: L = RoHS compliant silver-palladium-platinum-glass frit.
E = Halogen free component. RoHS compliant silver-
palladium-platinum-glass frit terminations.
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 (7500 parts per full reel).
2. Inductance measured using a Coilcraft SMD-A fixture in an Agilent/HP
4286A impedance analyzer with Coilcraft-provided correlation pieces.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at using an Agilent/HP 4291A with an Agilent/HP 16193
test fixture.
5. SRF measured using an Agilent/HP 8720D network analyzer and a
Coilcraft SMD-D test fixture.
6. DCR measured on a Cambridge Technology micro-ohmmeter and a
Coilcraft CCF840 test fixture.
7. Current that causes a 15°C temperature rise from 25°C ambient.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
The 0.055″ profile makes these parts ideal for low clear-
ance applications. Their simple construction ensures
high reliability and stability, and they feature much higher
SRF values than ferrite alternatives. For free evaluation
samples, visit www.coilcraft.com or contact Coilcraft.
