LB-403F1

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. !External dimensions (Units : mm) 26.0±0.4 6.75 10° 9.0 !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. 1.0 5.5 (22.86) Tolerances are ±0.3 unless otherwise noted: !Selection guide Emitting color Common Anode Red LB-403VF1 Green LB-403MF1 !Pin assignments 20 19 18 17 16 15 14 13 12 11 ++++++++++ a2 b1 c1 Digit 1 + Pin No. 1 + 2 + 3 f2 g2 e2 d2 Digit 2 + 4 + 5 + 6 + 7 b2 c2 a3 f3 g3 e3 d3 Digit 3 + 8 + 9 + 10 b3 c3 Pin No. 1 2 3 4 5 6 7 8 9 10 Function Segment "c1" Segment "e2" Segment "d2" Segment "g2" Segment "c2" Segment "e3" Segment "d3" Segment "g3" Segment "c3" NC Pin No. 11 12 13 14 15 16 17 18 19 20 Function Segment "b3" Segment "a3" Segment "f3" Digit 3 Common Digit 2 Common Segment "b2" Segment "a2" Segment "f2" Segment "b1" Digit 1 Common 3.0±0.5 φ0.5 (2.54) 8.0 φ0.5 (12.5) 1.0 10.0 16.0 LB-403F1 Series LED displays !Internal circuit schematic (example of common anode) Dig.1 20 COM Dig.2 15 COM Dig.3 14 COM b1 c1 19 1 a2 b2 c2 d2 e2 f2 g2 17 16 5 3 2 18 4 a3 b3 c3 d3 e3 f3 g3 12 11 9 7 6 13 8 !Absolute maximum ratings (Ta = 25°C) Red 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 LB-403VF1 640 40 15 60∗ 3 −25~+75 −30~+85 Green LB-403MF1 640 40 15 60∗ 3 Unit mW mW mA mA V °C °C ∗ Pulse width 1ms duty 1 / 5 !
