Carrier tape part #: TSSOP-08 Cover tape part #: Vendor determined. Reel size: 7 or 13 inch - Quantity dependent. All taping done in accordance with EIA 481 standards. Pieces taped with the marking up and showing through the cover tape (as shown in the above drawing). All orders under 100pcs, will be put on cut tape only with no leader or trailer. Labels will contain the TFT taped part number and quantity of pieces taped. Refer to the TFT Taped Part Numbering section for part numbers.
