Single Digit LED Numeric Display

Transcription

1 LA-40 D / N Series LED displays Single Digit LED Numeric Display LA-40 D / N Series LA-40 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 0.6mm, single digit LED Numeric Display that is packed by EPOXY resin. Dimensions (Unit : mm) (0.6) Features ) The height of a letter is 0.6mm. 2) Dimension is mm. 3) The package of surface color is black. Color of segment is colored in emitting color. ( color is only milky white) 4) Each color has anode common and cathode common respectively (.62) φ.0 3.Min (2.4) Tolerance are ±0.2 unless otherwise noted: Selection guide Emitting color Common Anode Cathode LA-40VD LA-40VN Orange Yellow LA-40AD LA-40AN LA-40ED LA-40EN LA-40XD LA-40XN LA-40MD LA-40MN LA-40BD LA-40BN Pin assignments Pin No. + a f b g e c + + d + D.P Pin No Function Common Segment "f" Segment "g" Segment "e" Segment "d" Common D.P Segment "c" Segment "b" Segment "a" Equivalent circuit (anode common) COM,6 (cathode common) COM,6 a 0 b 9 c 8 d e 4 f 2 g 3 D.P a 0 b 9 c 8 d e 4 f 2 g 3 D.P Rev.D /4
