High efficiency, two-digit numeric displays
LB-502DN Series
SIM-013STW1
Datasheet
The LB-502DN series were designed to meet the need for multi-digit numeric displays.
These LED numeric displays use GaAsP(red) , GaP(green) for the emitting material
(with the exception of green) and are housed in an epoxy resin package. They are two-digit displays
with a character height of 13.0mm.
lFeatures
1) Height of character : 13.0mm
2) Common anode and common cathode configurations are available for each color.
3) High efficiency reflectors are used to achieve a bright, clear display.
4) The package surface is painted black and the segments are colored the display color.
