LA-401BD ROHM

LA-401 D / N Series LED displays Single Digit LED Numeric Display LA-401 D / N Series z Dimensions (Unit : mm) LA-401 D / N series is developed because of the demand for small single digit LED Numeric Display. Materials of emission are GaAsP on GaP, AlGalnP GaP 9.6 and GaN. This is the height of a letter 10.16mm, single 10 digit LED Numeric Display that is packed by EPOXY resin. z Features 1.0 1.0 5.57 1) The height of a letter is 10.16mm. 2) Dimension is 9.613.07.0mm. 3) The package of surface color is black. Color of segment is colored in emitting color. (Blue color is only milky white) 0.25 4) Each color has anode common and cathode common (7.62) respectively. Tolerance are 0.2 unless otherwise noted: z Selection guide Emitting color Red Orange Yellow Red Green Blue High brightness High brightness High brightness Common Anode LA-401VD LA-401AD LA-401ED LA-401XD LA-401MD LA-401BD Cathode LA-401VN LA-401AN LA-401EN LA-401XN LA-401MN LA-401BN z Pin assignments Pin No. Function 1 Common Pin No. 2 Segment 1 + + 10 a Segment 3 4 Segment 2 + f + 9 b 5 Segment 3 + g + 8 6 Common 7 D.P 4 + + 7 ec 8 Segment 5 + + 6 d 9 Segment D.P Segment 10 z Equivalent circuit (anode common) (cathode common) COM COM 1,6 1,6 g g a b c d e f D.P a b c d e f D.P 10 9 8 5 4 2 3 7 10 9 8 5 4 2 3 7 Rev.D 1/4 1.0 3.5Min. 7.0 10.16 13.0 0.5 (2.54) (10.16)LA-401 D / N Series LED displays z Absolute maximum ratings (Ta=25C) Red Orange Yellow Red Green Blue High brightness High brightness High brightness Parameter Symbol Unit LA-401VD / VN LA-401AD / AN LA-401ED / EN LA-401XD / XN LA-401MD / MN LA-401BD / BN Power dissipation PD 320 520 520 520 480 336 mW Power dissipation 65 PD / seg 40 65 65 60 42 mW Forward current IF 15 25 25 25 20 10 mA 1 2 2 2 1 2 Peak forward current IFP 60 50 50 50 60 50 mA Reverse voltage V 5 5 5 5 5 5 V R Operating temperature Topr 25 to +75 C Storage temperature Tstg 30 to +85 C 1 Pulse width 1ms Duty 1 / 5 2 Pulse width 0.1ms Duty 1 / 10 z Electrical characteristics (Ta=25C) Red Orange Yellow Red Green Blue High brightness High brightness High brightness Parameter Symbol Conditions Unit Max.
