LA-401 D / N Series
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.

zFeatures
1) The height of a letter is 10.16mm.
2) Dimension is 9.6×13.0×7.0mm.
3) The package of surface color is black. Color of
segment is colored in emitting color. (Blue color is only
milky white)
4) Each color has anode common and cathode common
respectively.
