Notes

When ordering, please specify a packaging code: e.g. JA4220-ALC
Inductance measured at 1 MHz, 0.1 Vrms, 0 Adc on an Agilent/HP 4192 or equivalent.
DCR measured on a micro-ohmmeter at 25°C. For other operating temperatures, use this DCR at Temperature calculator.

Termination:

L = RoHS compliant tin-silver-copper over silver-platinum-glass frit.
S = non-RoHS tin-lead (63/37). (Special order, added cost)

Packaging:

C = 7″ machine-ready reel. EIA-481 embossed plastic tape (750 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 (3000 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.
