1. When ordering, please specify
termination
and
packaging
codes:
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.
Refer to Doc 362 “Soldering Surface Mount Components” before soldering.
