1. When ordering, please specify termination and packaging codes:
Z9280-ALC
Termination: L = RoHS compliant tin-silver-copper over silver-platinumglass frit.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: C = 7″ machine ready reel. EIA-481 embossed plastic
tape (250 parts per full reel).Quantities less than full
reel available: in tape (not machine ready) or withleader and trailer ($25 charge).
D = 13″ machine ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1000 parts per
full reel).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to C.

2. Impedance ratio is for the full primary winding to the full secondarywinding.
3. Electrical specifications at 25°C. Measurements are referenced to50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
