1. When ordering, please specify termination and packaging codes:
Z9280-ALC
Termination: L = RoHS compliant tin-silver-copper over silver-platinum-
glass 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).
B = Less than full reel. In tape, but not machine ready.
To have a leader and trailer added ($25 charge), use
code letter C instead.
D = 13″ machine ready reel. EIA-481 embossed plastic
tape. Factory order only, not stocked (1000 parts per
full reel).
2. Impedance ratio is for the full primary winding to the full secondary
winding.
3. Electrical specifications at 25°C. Measurements are referenced to
50 Ohms.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
