| LA-401DN Series LED displays High efficiency, single-digit numeric displays LA-401DN Series The LA-401DN series were designed to meet the need for small single-digit numeric displays. These LED numeric displays use GaAsP on GaP for the emitting material (with the exception of green) and are housed in an epoxy resin package. They are single-digit displays with a character height of 10.16 mm. External Dimensions (Units: mm) 9.6 10 Features 1) Height of character: 10.16 mm 2) Common anode and common cathode configurations are available for each color. 3) Each segment has independent pin connections and static drive is possible. 4) High-efficiency reflectors are used to achieve a bright, clear display. 5) The package surface is painted black and the segments are colored the display color. 1.0 5.57 1.0 (7.62) Tolerances are 0.2 unless otherwise noted : Selection guide Emitting color Red Common Anode LA-401VD LA-401DD LA-401DN LA-401MD LA-401MN Orange Green LA-401VN Cathode Order-based production.
