Single Digit LED Numeric Display
LA-401 D / N Series
LA-401 D / N series is developed because of the
demand for small single digit LED Numeric Display.
Materials of emission are GaAsP on GaP, AlGalnP GaP
and GaN. This is the height of a letter 10.16mm, single
digit LED Numeric Display that is packed by EPOXY
resin.
