High efficiency, three-digit Numeric Display LB-603 FP Series The LB-603 FP 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 14.3mm. Dimensions (Unit : mm) 37.5 12.5 12.5 2.5Min. 8.0 Features 1) Height of character : 14.3mm. 2) The package surface is painted black and the segments are colored the display color. 3) High efficiency reflectors are used to achieve a bright, clear display. 0.25 3-φ1.5 1.3 8.0 (15.24) 1.3 14.3 18.0 10 0.5 (2.54) (33.02) Tolerance are ±0.2 unless otherwise noted : Selection guide Emitting color Common Anode Cathode Red Green LB-603VF LB-603VP LB-603MF LB-603MP Pin assignments 28 27 26 25 24 23 22 21 20 19 18 17 16 15 a1 f1 g1 e1 d1 g2 e2 c1 Digit 2 D.P2 Digit 1 D.P1 Pin No. 1 2 3 4 5 f3 b2 6 g3 e3 c2 d2 7 8 1 2 3 4 5 6 7 8 9 10 11 12 13 14 a3 a2 f2 b1 Pin No. b3 c3 d3 Digit 3 D.P3 9 10 11 12 13 14 Function Pin No. Segment "e1" Segment "d1" Digit 1 Common Segment "c1" D.P1 Segment "e2" Segment "d2" Segment "c2" D.P2 Segment "e3" Segment "d3" Segment "g3" Segment "c3" D.P3 15 16 17 18 19 20 21 22 23 24 25 26 27 28 Function Segment "b3" Segment "a3" Segment "f 3" Digit 3 Common Digit 2 Common Segment "b2" Segment "a2" Segment "g2" Segment "f 2" Segment "b1" Segment "a1" Digit 1 Common Segment "f 1" Segment "g1" Equivalent circuit (anode common) Dig.1 3,26 COM a1 b1 c1 d1 e1 f1 g1 D.P1 25 24 4 2 1 27 28 5 Dig.2 19 COM a2 b2 c2 d2 e2 f2 g2 D.P2 21 20 8 7 6 23 22 9 www.rohm.com c 2011 ROHM Co., Ltd.
