Notes

When ordering, please specify tolerance, terminations and packaging codes: e.g. 1812PS-105JRC
Inductance measured at 100 kHz, 0.1 Vrms, using Coilcraft SMD-A fixture in Agilent/HP 4263B LCR meter or equivalent.
Tolerances in bold are stocked for immediate shipment
DCR measured on micro-ohmmeter and a Coilcraft CCF840 test fixture. For other operating temperatures, use this DCR at Temperature calculator.
SRF measured using an Agilent/HP 8753D network analyzer and a SMD-D test fixture test fixture.
Isat: DC current at which the inductance drops 10% (typ.) from its value without current.
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.

Tolerance:

J = 5%, K = 10% (Table above shows stock tolerances in bold.)

Termination:

R = Halogen free component. Matte tin over nickel over silver-platinum-glass frit.
L = RoHS compliant, not halogen-free. Silver-palladium-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″ machine-ready reel. 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.
