Light Emitting Diodes displays The LA-301 BL series were designed to meet the need for 8 mm 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 8 mm. @Features 1) Large display with small exterior dimensions. Compact package with little worri- some light leakage from segment. Red, orange, yellow, and green are available in common anode and common cathode configura- tions. } The package surface is coated black and the segments are col- ored the display color. 2) 3) LA-301 BL Series @External dimensions (Unit: mm) High efficiency, single-digit numeric 7.0 | 10"!
