1 When ordering, please specify tolerance and packaging codes: e.g. 1812PS-105JLC
Tolerance: J = 5%, K = 10%  (Table above shows stock tolerances in bold.)
Packaging: C = 7" machine-ready reel
EIA RS-481 clear plastic tape (600 parts per full reel).
B = Less than full reel
In tape, not machine ready. To have a leader and trailer added ($25 charge), use code letter C instead.
D = 13" reel, machine-ready 
EIA RS-481 clear plastic tape. Factory order only, not stocked (2200 parts per full reel).
2 Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B LCR meter or equivalent.
3 Tolerances in bold are stocked for immediate shipment
4 Q measured on an Agilent/HP 4291 with an Agilent/HP 16193 test fixture.
5 DCR measured on 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 SMD-D test fixture test fixture. Details
7 Isat: DC current at which the inductance drops 10% (typ.) from its value without current. Details
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.
9 Ambient temperature range: −40°C to +105°C with Irms current.
10 Maximum part temperature: +145°C (Ambient + temperature rise)
11 Storage temperature range: Component: −40°C to +145°C
Tape and reel packaging: −40°C to +80°C
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.
