1. When ordering, please specify tolerance and packaging codes:
1812FS-105JLC
Tolerance: J =5% K = 10%
(Table shows stock tolerances in bold.)
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 maximum ratings. Click for temperature derating information.
9. Electrical specifications at 25°C.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
