Tape and Reel Specifications: All case sizes are available on

plastic embossed tape per EIA-481-1. Tape reeling per IEC 286-3

is also available. Standard reel diameter is 7" [178 mm],

13" [330 mm] reels are available and recommended as the most

cost effective packaging method.

The most efficient packaging quantities are full reel increments on

a given reel diameter. The quantities shown allow for the sealed

empty pockets required to be in conformance with EIA-481-1. Reel

size and packaging orientation must be specified in the Vishay

Sprague part number.
