LB-502VD ROHM

High efficiency, two-digit numeric displays LB-502DN Series 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. Features 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.
