The LA-401 DN series were designed to numeric displays. These LED numeric displays use GaAsP on GaP for the emitting material (with the exception of resin package. They are single-digit displays with a character height of 10.16 mm. @Features 1) Light Emitting Diodes High efficiency, single-digit numeric displays LA-401 DN Series @External dimensions (Unit: mm) meet the need for small single-digit green) and are housed in an epoxy Height of character : 10.16 mm. | _(10.16) f \ 2) Common anode and common i |e cathode configurations are avail- 1+ oot able for each color. 0,25 4 3) Each segment has independent van| 2 pin connections and static drive is ~ possible.
