LA-501DN Series
The LA-501DN series were designed to meet
the need for 13mm single-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 single-digit
displays with a character height of 13.0mm.
