LA-301BL Series
LED displays
High efficiency, single-digit numeric
displays
LA-301BL Series
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.
Features
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.
