1. When ordering, specify tolerance, termination and packaging codes:
Designer’s Kit C414 contains 10 of each 5% value
1008AF-103XJLC
Tolerance:J = 5% K = 10%
(Table shows stock tolerances in bold.)
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 2.5 MHz using 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 2.5 MHz using an Agilent/HP 4291A with an Agilent/HP
16193 test fixture.
5. SRF measured using an Agilent/HP 8753D network analyzer with a
Coilcraft SMD-D fixture.
6. DCR measured on a Cambridge Technology Micro-ohmmeter.
7. DC current at 25°C that causes an inductance drop of 10% (typ) from its
value without current. Click for temperature derating information.
8. Current that causes a 40°C temperature rise from 25°C ambient. This
information is for reference only and does not represent absolute maximum ratings. Click for temperature derating information.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
