1. When ordering, please specify packaging code:
NA5936-ALD
Packaging: D = 13″ machine-ready reel. EIA-481 embossed plastic tape(800 parts per full reel). Quantities less than full reelavailable: in tape (not machine ready) or with leader andtrailer ($25 charge).
B = Less than full reel. In an effort to simplify our partnumbering system, Coilcraft is eliminating the needfor multiple packaging codes. When ordering, simply
change the last letter of your part number from B to D.
