1 When ordering, please specify termination and packaging codes: e.g. Z9280-ALC
Termination: L = RoHS compliant tin-silver-copper over silver-platinum-glass frit
Special order, added cost: S = non-RoHS tin-lead (63/37).
Packaging: C = 7" reel, machine-ready 
EIA-481 embossed plastic tape, special order (250 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-481 embossed plastic tape. Factory order, not stocked (1000 parts per full reel).
2 Impedance ratio is for the full primary winding to the full secondary winding.
3 DCR at 25°C. For other operating temperatures, use this DCR at Temperature calculator.
4 Ambient temperature range: −40°C to +85°C
5 Storage temperature range: Component: −40°C to +85°C
Tape and reel packaging: −40°C to +80°C
6 Electrical specifications at 25°C. Measurements are referenced to 50 Ohms.
Refer to Soldering Coilcraft Components before soldering.
PCB washing: Tested to MIL-STD-202 Method 215 plus an additional aqueous wash. More info.
