0.4" Seven-Segment Numeric LED Display
LTS-4X01A LTD-4000 Series LTC-4000
Features
0.4 inch (10.0mm) digit height. Choices of five bright colors: AlGaAs red/bright red/green/yellow/red orange. Low power requirement. Excellent characters appearance. Categorized for luminous intensity. I.C. compatiable. Easy mounting on P.C. board or socket.
Descriptions
The LTS-4X01A, LTD-4000, LTC-4000 series are 0.4 inch (10.0mm) height single, dual, triple and quadruple digit displays. These devices have gray face and white segments. The AlGaAs red seven segment displys are designed for applications requiring low power consumption. They are tested and selected for the excellent low current characteristics to ensure that the segments are matched at low current. Drive current as low as 1 mA per segment is available. The AlGaAs red series devices utilize LED chips which are made from AlGaAs on a non-transparent GaAs substrate. The bright red and green series devices utilize LED chips which are made from GaP on a transparent GaPsubstrate. The yellow and red orange series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate. All devices have gray face and white segments.
