LED displays
High efficiency, three-digit numeric
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 14.3 mm.
External dimensions
(Units: mm)
1) Height of character : 14.3 mm.
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.
