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.
