LL-34 (Mini-MELF) Tape & Reel Packaging Information Label Antistatic Cover Tape Static Dissipative Embossed Carrier Tape Cathode Label LL34 UNIT ORIENTATION Carrier Tape Cover Tape Trailer Tape 80mm minimum or 20 empty pockets. Leader Tape 500mm minimum or 125 empty pockets. Components Packaging Description: LL34 parts are shipped in tape and reel. The carrier tape is made from a dissipative (carton filled) polycarbonate resin. The cover tape is a multiplayer film (Heat Activated Adhesive in nature) primarily composed of polyester film, adhesive layer, sealant, and anti-static sprayed agent. These reeled parts in standard option are shipped with 2,500 units per 7” or 178cm diameter reel. The reels are blue in color and made of recyclable plastic. Other option comes in 10,000 units per 13” or 330cm diameter reel LL-34 Packaging Outline LL-34 Leader and Trailer
