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.

Core material Ferrite

Terminations RoHS compliant tin-silver-copper over silver-platinum-

glass frit. Other terminations available at additional cost.
