| LB-203BL Series LED displays High efficiency, three-digit numeric displays LB-203BL Series The LB-203BL series are small, three-digit numeric displays with a character height of 6.4mm. These displays can be combined with appropriate displays in the two-digit LB-202BL series to form a multi-digit display with an equal pitch interval between characters. !External Dimensions (Units : mm) +0 19.2 -0.2 6.4 6.4 10 0.7 6.4 15.0 +0 -0.2 !Features 1) Four colors are available : red, orange, yellow, and green. 2) Common anode and common cathode configurations are available. 3) Dynamic lighting system to minimize the number of pins. 4) Equal pitch interval between characters even with multi-digit display. 5) The package surface is painted black and the segments are colored the display color. 0.7 3.4 3-0.7 0.5 (2.54) (12.7) Tolerances are 0.3 unless otherwise noted : !Selection guide Emitting color Red Common Anode LB-203VB LB-203DB LB-203DL LB-203YB LB-203YL LB-203MB LB-203ML Orange Yellow Green LB-203VL Cathode Order-based production. !Pin assignments 12 + a f g c b f 11 + 10 + a g c b f 9 + 8 + a g c b 7 + Pin No. 1 2 3 4 5 6 7 8 9 10 11 12 Function Digit 1 Common Segment "e" Segment "d" Segment "c" D.P N.C Digit 3 Common Digit 2 Common Segment "g" Segment "b" Segment "a" Segment "f" e d e d e d Digit 1 D.P1 + Pin No. 1 + 2 Digit 2 D.P2 + 3 + 4 Digit 3 D.P3 + 5 + 6 7.9Min. 5.5+0 -0.2 0.3 (12.2) LB-203BL Series LED displays !Internal circuit schematic (example of common cathode) Dig.1 1 Dig.2 8 Dig.3 7 5 9 12 2 D.P g f e 3 4 10 11 dcba !Absolute maximum ratings (Ta=25C) Parameter Power dissipation Power dissipation Forward current Peak forward current Reverse voltage Operating temperature Storage temperature Symbol PD PD / seg IF IFP VR Topr Tstg Red Orange Yellow Green Unit mW mW mA mA V C C LB-203VB / VL LB-203DB / DL LB-203YB / YL LB-203MB / ML 960 40 15 60 3 960 40 15 60 3 -25+75 -30+85 960 40 15 60 3 960 60 15 60 3 Pulse width 1ms duty 1 / 5 !Electrical and optical characteristics (Ta=25C) Parameter Forward voltage Reverse current Peak wavelength Spectral line half width Symbol Conditions Min.
