ÿþLD-701 Series LED displays Large flat displays LD-701 Series The LD-701 series were designed in External dimensions (Units : mm) response to the need for large, flat displays. These are three-chip, flat displays with high luminance. 21.0 19.8±0.1 Features 1) Three independent chip elements. 2) Large 4.5 x 19.8 mm emission area. 3) Thin outer casing, multiple units can be coupled together. 4) Four colors are available: red, orange, 0.6 Pin No.1 2 3 4 5 6 yellow and green. Pin No.1 2 3 4 5 6 (2.5) (7.0) (7.0) Tolerances are ±0.3 unless otherwise noted: Selection guide Emitting color Red Orange Yellow Green Type LD-701VR LD-701DU" LD-701YY" LD-701MG "Order-based production.

Operation notes When forming leads, the bend should be at least 2mm from the base of the package. Solder after forming the leads, and ensure that the inside of the LED is not subjected to mechanical stress while it is hot. Axial Luminous Intensity
