1. When ordering, please specify
tolerance, termination,
and
packaging
codes:
1812FS-105JLC
J
= 5%
K
= 10%
(Table shows stock tolerances in bold.)
Termination: L
=
RoHS compliant silver-palladium-platinum-glass frit.
R
= Matte tin over nickel over silver-platinum-glass frit.
Packaging: C
= 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel).
B
= Less than full reel. On tape, but not machine ready.
To have a leader and a trailer added ($25 charge),
use code letter C instead.
D
= 13″ machine-ready reel. EIA-481 embossed plastic
tape (2200 parts per full reel).
2. Inductance measured at 100 kHz, 0.1 Vrms, 0 Adc using a Coilcraft
SMD-A fixture in an Agilent/HP 4263B impedance analyzer.
3. Tolerances in bold are stocked for immediate shipment.
4. Q measured at 1 MHz on an Agilent/HP 4291A with an Agilent/
HP 16193 test fixture.
5. DCR measured on a micro-ohmmeter and a Coilcraft CCF840 test
fixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and a
Coilcraft SMD-D test fixture.
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 maxi-
mum ratings.
Click for temperature derating information.
9. Electrical specifications at 25°C.
