High efficiency, three-digit LED Numeric Display LB-603 FP Series Datasheet The LB-603 FP 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 three-digit displays with a character height of 14.3mm. Features 1) Height of character : 14.3mm. 2) The package surface is painted black and the segments are colored the display color. 3) High efficiency reflectors are used to achieve a bright, clear display.
