(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 probable 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 anodecathode emitting color c ommon red lap-401vdlap-401vn orange lap-401ddLAP-401DN yellow lap-401ydlap-401yn green lap-401mdlap-401mn ? pin assignments p in no. 1 + 2 + 3 + 4 + 5 1 0 98 7 6 + ++ + + + a g d f b ec d.p function pin no. 12 3 4 5 6 7 8 9 10 commonsegment "f" segment "g" segment "e" segment "d" common d.p segment "c" segment "b" segment "a" ? inner circuit (anode common) com 1,6 a 1 0 b9 c 8 d5 e4 f 2 g3 d .p 7 com 1,6 a 1 0 b9 c 8 d5 e4 f 2 g3 d .p 7 10? 13.0 10.16 1.0 1.0 0.5 (10.16) 0.25 (7.62) 7.0 3.5min. 5.57 9.6 1.0 (2.54) tolerance are 0.2 unless otherwise noted: downloaded from: http:///
