1. Whenordering, pleasespecifyterminationand packagingcodes:
Z9280-ALD
Termination: L = RoHS compliant tin-silver-copper over silver-
platinum-glass frit.
Special order: S = non-RoHS tin-lead (63/37).
Packaging: D = 13″ machine ready reel. EIA-481 embossed plastic
tape, 1000 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 D instead.
2. Impedance ratio is for the full primary winding to the full secondary
winding.
3. Electrical specifications at 25°C.
