Single Digit LED Numeric Display
LA-301 B / L Series
zDimensions (Unit : mm)
LA-301 B / L 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 8mm, single digit LED
Numeric Display that is packed by epoxy resin.

zFeatures
1) The height of a letter is 8mm.
2) The light don’t leak from the segment in spite of the
small package.
