1. When ordering, please specify
termination
and
packaging
codes:
1008LS-103XJLC
Termination: 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).
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 at 7.9 MHz using 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 ambient.
Because of their open construction, these parts will not saturate.
7. Electrical specifications at 25°C.
See Qualification Standards section for environmental and test data.
For part marking data see Color Coding section.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
