R = Halogen free component. Matte tin over nickel over
silver-platinum-glass frit terminations.
Packaging:
C = 7″ machine-ready reel. EIA-481 embossed plastic tape
(600 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 (2200 parts per full
reel).
