LB-402VN

High efficiency, two-digit numeric displays LB-402DN Series The LB-402 DN 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 two-digit displays with a character height of 10.16 mm. Features 1) Height of character : 10.16 mm 2) Common anode and common cathode configurations are available for each color. 3) The package surface is painted black and the segments are colored the display color. 4) High efficiency reflectors are used to achieve a bright, clear display. Dimensions (Unit : mm) 24.0 12.0 10° 1.0 10.16 18.0 1.0 5.57 2-φ 1.0 (20.32) Tolerances are ±0.2 unless otherwise noted: Selection guide Emitting color Common Anode Cathode Red LB-402VD LB-402VN Green LB-402MD LB-402MN Pin assignments 18 17 16 15 ++++ a1 14 13 12 11 10 +++++ a2 f2 g2 Pin No. 1 2 3 4 5 6 7 8 9 Function Segment "e1" Segment "d1" Segment "c1" D.P1 Segment "e2" Segment "d2" Segment "g2" Segment "c2" D.P2 Pin No. 10 11 12 13 14 15 16 17 18 Function Segment "b2" Segment "a2" Segment "f2" Digit 2 Common Digit 1 Common Segment "b1" Segment "a1" Segment "g1" Segment "f1" f1 g1 e1 d1 b1 b2 c1 Digit 1 D.P1 2 3 e2 d2 c2 Digit 2 D.P2 7 8 9 ++++ Pin No. 1 4 + 5 ++++ 6 www.rohm.com c ○ 2011 ROHM Co., Ltd.
