LA-301BL Series LED displays High efficiency, single-digit numeric displays LA-301BL Series zExternal Dimensions (Units: mm) 7.0 +0.1 0.25 0 (5.3) 11.0 3.80.5 5.0 0.8 +0.1 0.5 0 (2.0) 1.0 4.0 zFeatures 1) Large display with small exterior dimensions. 2) Compact package with little worrisome light leakage from segment. 3) Red, orange, yellow, and green are available in common anode and common cathode configurations. 4) The package surface is painted black and the segments are colored the display color. (8.0) 10 1.0 8.0 The LA-301BL 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. Tolerances are 0.3 unless otherwise noted : zSelection guide Emitting color Red Orange Yellow Green LA-301VB LA-301DB LA-301YB LA-301MB LA-301VL Cathode Order-based production.
