lb-403f1 series led displays high efficiency, three-digit numeric displays lb-403f1 series the lb-403 f1 series were designed to meet the need for multi-digit numeric displays. these led numeric displays use gaasp on gap for the emitting material (with the exception of green) and are housed in an epoxy resin package. they are three-digit displays with a character height of 10 mm. ! ! ! ! features 1) height of character : 10mm. 2) common anode configuration available for each color. 3) high efficiency reflectors are used to achieve a bright, clear display. 4) the package surface is painted black and the segments are colored the display color. ! ! ! ! external dimensions (units : mm) 5.5 0.5 (12.5) 16.0 1.0 10.0 26.0 0.4 10 (22.86) (2.54) 1.0 0.5 8.0 3.0 0.5 6.75 9.0 tolerances are 0.3 unless otherwise noted: ! ! ! ! selection guide red green lb-403vf1 LB-403MF1 anode common emitting color ! ! ! ! pin assignments digit 2 digit 1 a2 g2 d2 f2 b2 c2 b1 c1 e2 digit 3 a3 g3 d3 f3 b3 c3 e3 pin no. 1 2 3 4 5 6 7 8 9 10 20 19 18 17 16 15 14 13 12 11 + + + + + + + + + + + + + + + + + + + + segment "c1" segment "e2" segment "d2" segment "g2" segment "c2" segment "e3" segment "d3" segment "g3" segment "c3" nc 1 2 3 4 5 6 7 8 9 10 function pin no. segment "b3" segment "a3" segment "f3" digit 3 common digit 2 common segment "b2" segment "a2" segment "f2" segment "b1" digit 1 common 11 12 13 14 15 16 17 18 19 20 function pin no.
