The device conforms to a standard EIA package footprint. Detailed dimensional drawings are provided in the datasheet, with all dimensions in millimeters and a general tolerance of ±0.2 mm. The cathode is typically identified by a marking on the package or a specific pad geometry on the tape. The recommended PCB attachment pad layout for infrared or vapor phase reflow soldering is also specified to ensure proper solder joint formation and mechanical stability.

.2 Tape and Reel Packaging

The LEDs are supplied in embossed carrier tape with a protective cover tape, wound onto 7-inch (178 mm) diameter reels. Each reel contains 2000 pieces. The packaging follows ANSI/EIA 481 specifications. Key notes include: empty component pockets are sealed, and a maximum of two consecutive missing components ("lamps") is allowed per reel.
