1. When ordering, please specify tolerance, termination, and packaging
codes:
1812FS-105JRC
J = 5% K = 10%(Table shows stock tolerances in bold.)
Termination: R = RoHS compliant matte tin over nickel over silverplatinum-glass frit.
L = RoHS compliant silver-palladium-platinum-glass frit.
Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic
tape (600 parts per full reel). Quantities less thanfull reel available: in tape (not machine ready) orwith leader and trailer ($25 charge).
D = 13″ machine-ready reel. EIA-481 embossed plastictape. Factory order only, not stocked (2200 partsper full reel).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating theneed for multiple packaging codes. When ordering,simply change the last letter of your part number
from B to C.
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 testfixture.
6. SRF measured using an Agilent/HP 8753D network analyzer and aCoilcraft SMD‑D test fixture.
7. DC current at 25°C that causes an inductance drop of 10% (typ) fromits 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.
