(in case of orange color) 3) the same luminous intensity as the conventional products at their 1/10 of current, which contributes lots to energy-saving of sets. 4)light-leakage from segments pr obable with the small display packages is very rare. 5)both anode common type and cathode common type are available in lineup for each color. ? selection guide anode cathode emitting color common red lbp-602va2 lbp-602vk2 orange lbp-602da2 lbp-602dk2 yellow lbp-602ya2 lbp-602yk2 green lbp-602ma 2 lbp-602mk 2 ? pin assignments d.p1 d.p2 a1 g1 digit 1 f1 b1 e1 c1 a2 g2 digit 2 f2 b2 e2 c2 d1 d2 p in no. 1 2 3 4 5 6 7 8 9 18 17 16 15 14 13 12 11 10 + + + + + + + + + + + + + + + + + + segment "e1" segment "d1" segment "c1" d.p1 segment "e2" segment "d2" segment "g2" segment "c2" d.p2 1 2 3 4 5 6 7 8 9 function pin no. segment "b2" segment "a2" segment "f2" digit 2 commo n digit 1 commo n segment "b1" segment "a1" segment "g1" segment "f1" 10 11 12 13 14 15 16 17 18 function pin no. ? inner circuit (anode common) (cathode common) a 1 1 6 b1 15 c1 3 d1 2 e1 1 f1 18 g1 17 d.p1 4 a2 11 b2 10 c2 8 d2 6 e2 5 f2 12 g2 7 d.p2 9 14 dig.1 com 13 dig.2 com a1 16 b1 15 c1 3 d1 2 e1 1 f1 18 g1 17 d.p1 4 a2 11 b2 10 c2 8 d2 6 e2 5 f2 12 g2 7 d.p 2 9 14 dig.1 com 13 dig.2 com 12.5 25.0 0.1 19.0 0.1 14.3 1.3 8.0 1.3 8.0 0.5 (2.54) (20.32) 2 ? 1.5 10 (15.24) 0.25 3.5min. tolerance are 0.3 unless otherwise noted :
