| LA-101AK Series LED displays High efficiency, single-digit numeric displays LA-101AK Series The LA-101AK series are LED numerical displays designed to allow use even in bright locations. The height of the character is 25.4 mm, and two colors are available: red and green. These displays are designed for use in large numerical displays. !External Dimensions (Units: mm) 24.00.2 10 2.5 25.4 34.00.2 (10.16) Tolerances are 0.3 unless otherwise noted : !Selection guide Emitting color Red Common Anode Cathode LA-101VA LA-101VK LA-101MA LA-101MK Green !Pin assignments 10 9 8 7 6 +++++ a f g c b Pin No. 1 2 3 4 5 6 7 8 9 10 Function Segment "e" Segment "d" Common Segment "c" D.P Segment "b" Segment "a" Common Segment "f" Segment "g" e + Pin No. 1 d D.P ++++ 2345 3.5Min. !Features 1) Height of character: 25.4 mm 2) Dimensions: 24 x 34 x 10.5 mm 3) A common anode configuration and a common cathode configuration are available for each color. 4) The package surface is painted black and the segments are colored the display color. 5) High luminance, clear display. 2.5 14.1 3.2 0.5 (2.54) 10.50.2 (30.5) LA-101AK Series LED displays !Internal circuit schematic (example of common cathode) COM 3,8 abcdefg 7 6 4 2 1 9 10 D.P 5 !Absolute maximum ratings (Ta=25C) 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 mW mW mA mA V C C LA-101VA / VK LA-101MA / MK 640 85 (45) 15 60 6 (3) -25+75 -30+85 640 85 (45) 20 60 6 (3) Pulse width 1ms duty 1 / 5 ( ) is D.P value !Electrical and optical characteristics (Ta=25C) Parameter Forward voltage Reverse current Peak wavelength Spectral line half width Symbol Conditions Min.
