Example Part Number





Three digit induction code. The first two are significant. The last one is the multiplication factor (the number of zeroes).
1.2µH = 1200nH = 12 significant with two zeroes = 122


E = RoHS compliant tin-silver over copper.
Special order:
T = RoHS tin-silver-copper (95.5/4/0.5)
S = non-RoHS tin-lead (63/37).


C = 7″ machine-ready reel. EIA-481 embossed plastic tape. 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
B = Less than full reel. In an effort to simplify our part numbering system, Coilcraft is
elimnating the need for multiple packaging codes. When ordering, simply change the
last letter of your part number from B to C.
