High efficiency, three-digit numeric
displays
LB-403F1 Series
The LB-403 F1 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 10 mm.
