1. When ordering, please specify
tolerance
and
packaging
codes:
1008CT-101XJBC
Tolerance: F
= 1%
G
= 2%
J
= 5%
K
= 10%
M
= 20%
(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).
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.
