1. When ordering, please specify packaging code:

KA4947-AEC

Packaging: C = 7″ machine-ready reel. EIA-481 embossed plastic

tape (250 parts per full reel).

103B

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).
