Rohm LB-603MP High efficiency, three-digit numeric display Datasheet

High efficiency, three-digit Numeric Display
LB-603 FP Series
The LB-603 FP series were designed to meet the need for
multi-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 three-digit displays with a character
height of 14.3mm.
