LB-402

LB-402FP Series LED displays High efficiency, two-digit numeric displays LB-402FP Series The LB-402FP series were designed to meet the need for multi-digit numeric displays. Featuring excellent visibility, these two-digit LED numeric displays have a character height of 10mm. A colored cover case is attached to the surface of the display. !External dimensions (Units : mm) C0.6 10° 9.0 1.0 !Features 1) Two colors are available: red and green. 2) Common anode and common cathode configurations are available. 3) Each segment has independent pin connections and making static drive is possible. 4) Excellent visibility. Uniform brightness. Wide view angle. Character shapes cannot be seen when not illuminated. 22.0 8.0 0.7 (2.5) (17.5) 3±0.5 Tolerances are ±0.3 unless otherwise noted: !Selection guide Emitting color Red Common Anode Cathode LB-402VF LB-402VP LB-402MF LB-402MP Green !Pin assignments 16 15 14 13 12 11 10 9 + + + a1 + + + + a2 + f1 g1 e1 b1 f2 g2 c1 e2 b2 c2 d1 Dig.1 d2 Dig.2 + Pin No. 1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 Pin No. 1 2 3 4 5 6 7 8 Function Segment "c1" Segment "e1" Segment "d1" Digit1 Common Digit2 Common Segment "d2" Segment "e2" Segment "c2" Pin No. 9 10 11 12 13 14 15 16 Function Segment "g2" Segment "a2" Segment "f2" Segment "b2" Segment "b1" Segment "f1" Segment "a1" Segment "g1" 16−φ0.5 1.0 5.56 (12.5) 10.0 16.0 LB-402FP Series LED displays !Internal circuit schematic (example of common anode) a1 15 b1 13 c1 1 d1 3 e1 2 f1 14 g1 16 a2 10 b2 12 c2 8 d2 6 e2 7 f2 11 g2 9 4 Dig.1 COM 5 Dig.2 COM !Absolute maximum ratings (Ta = 25°C) 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 Green Unit 840 60 20 60 5 −25~+75 −30~+85 mA mW / seg mA mA ∗ V °C °C LB-402VF / VP LB-402MF / MP 840 60 20 60 5 ∗ Pulse width 1ms duty 1 / 5 !
