1. When ordering, please specify
termination
and
packaging
codes:
1008LS-103XJEC
Termination: E
= Halogen free component. RoHS compliant silver-
palladium-platinum-glass frit terminations.
L
= RoHS compliant, not halogen-free. 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. Factory order only, not stocked (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. Q measured using an Agilent/HP 4291A with an Agilent/HP 16193 test
fixture.
4. SRF measured using an Agilent/HP 8753D network analyzer with a
Coilcraft SMD-D fixture.
5. DCR measured on a Cambridge Technology Micro-ohmmeter.
6. Current that causes a 15°C temperature rise from 25°C. Because of
their open construction, these parts will not saturate. This information is
for reference only and does not represent absolute maximum ratings.
7. Current production parts are marked with one dot. Prior production parts
were marked with three dots. Single color dots are not unique identifiers
and correspond to multiple inductance values. Part marking does not
indicate polarity.
8. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
