1 When ordering, please specify tolerance, termination, and packaging codes: e.g. 1812FS-105KLC
Tolerance: J = 5%, K = 10% (Table above shows stock tolerances in bold.)
Termination: L= RoHS compliant silver-palladium-platinum-glass frit.
R = RoHS compliant 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). Quantities less than full reel available: in tape (not machine ready) or with leader and trailer ($25 charge).
D = 13" reel, machine-ready 
EIA-481 embossed plastic tape. Factory order only, not stocked (2200 parts per full reel).
B = Less than full reel
In an effort to simplify our part numbering system, Coilcraft is eliminating the need 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, using a Coilcraft SMD-A fixture in an Agilent/HP 4263B LCR meter or equivalent.
3 Tolerances in bold are stocked for immediate shipment.
4 Q measured at 1 MHz using an Agilent/HP 4291A with an Agilent/HP 16193 test fixture.
5 DCR measured at 25°C on a micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
6 SRF measured using an Agilent/HP 8753D network analyzer and a Coilcraft SMD-D test fixture. Details
7 Isat: DC current at which the inductance drops 10% (typ.) from its value without current.
Temperature derating curves.
8 Irms: 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. Temperature derating curves.
9 Ambient temperature range: −40°C to +85°C with Irms current.
10 Storage temperature range: Component: −40°C to +125°C
Tape and reel packaging: −40°C to +80°C
11 Maximum part temperature: +125°C (Ambient + temperature rise)
12 Resistance to soldering heat: Three reflows at >217°C for 90 seconds (+260°C ±5°C for 20 – 40 seconds), allowing parts to cool to room temperature between.
13 Electrical specifications at 25°C.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
