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. Average current for a 15°C rise above 25°C ambient.
8. Operating temperature range −40°C to +125°C.
9. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
For part marking data see Color Coding section.
1. When ordering, please specify tolerance and packaging codes:
1008CT-101XJBC
Tolerance: F =1% G = 2% J = 5%
(Table shows stock tolerances in bold.)
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).
The 0.055″ profile makes these parts ideal for low
clearance applications. Their simple construction en-
sures 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.
