LB-402VD ROHM

High efficiency, two-digit numeric displays LB-402DN Series Datasheet The LB-402 DN series were designed to meet the need for multi-digit numeric displays. These LED numeric displays use GaAsP on GaP (red), GaP(green) for the emitting material and are housed in an epoxy resin package. They are two-digit displays with a character height of 10.16 mm. Features 1) Height of character : 10.16 mm 2) Common anode and common cathode configurations are available for each color. 3) The package surface is painted black and the segments are colored the display color. 4) High efficiency reflectors are used to achieve a bright, clear display.
