Single Digit LED Numeric Display
LA-301 B / L Series
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. Dimensions (Unit : mm)
7.0 10˚
1.0
Features 1) The height of a letter is 8mm. 2) The light don’t leak from the segment in spite of the small package. 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.
