Single Digit LED Numeric Display LAP-401 D / N Series LAP-401 D / N series are the numberical display units featuring ROHM’s in-house 4-element(AlGaInP) high-brightness LED dies.Their luminous intensity is top class in the industry while degradation is considerably slow, which helps to keep illumination vividness almost unchanged and the image of sets high over a long period of time. Dimensions (Unit : mm) 9.6 (10.16) 0.5 φ1.0 0.25 (7.62) 3.5Min. 7.0 1.0 5.57 (2.54) Features 1) 10.16mm for letter height, single-line LED numerical displays. 2) About 10 times more luminous intensity than the conventional products by use of 4-element LED dies. (in case of orange color) 3)The same luminous intensity as the conventional products at their 1/10 of current, which contributes lots to energy-saving of sets. 4) Light-leakage from segments probable with the small display packages is very rare. 5)Both anode common type and cathode common type are available in lineup for each color. 13.0 1.0 10.16 10˚ Tolerance are ±0.2 unless otherwise noted: Selection guide Emitting color Common Anode Cathode Red Orange Yellow Green LAP-401VD LAP-401VN LAP-401DD LAP-401DN LAP-401YD LAP-401YN LAP-401MD LAP-401MN Pin assignments Function Pin No. Pin No. 1 + f b 3 + 4 + + 10 a 2 + + 8 g e 5 + + 9 + 7 c + 6 d D.P 1 2 3 4 5 6 7 8 9 10 Common Segment "f" Segment "g" Segment "e" Segment "d" Common D.P Segment "c" Segment "b" Segment "a" Inner circuit (anode common) COM 1,6 a b c d e f g D.P 10 9 8 5 4 2 3 7 www.rohm.com c 2010 ROHM Co., Ltd.
