0.3" Single Digit Numeric LED Displays LTS-310A Features Series Package Dimensions 0.3 inch (7.62mm) digit height. Choices of six bright colors-AlGaAs red/bright red/ green/yellow/red orange/high efficiency red. Low power requirement. Excellent characters appearance. Categorized for luminous intensity. I.C. compatiable. Easy mounting on P.C. board or socket. A.LTS-312A/313A/315A Descriptions The LTS-310A series are 0.3 inch (7.62mm) height single digit displays. AlGaAs red desplays has gray face and white segments. Bright red displays has black face and red segments. Green and yellow displays have gray face and white segments. Red orange displays have orange face and orange segments. The High efficiency red displays have red face and red segments. The AlGaAs red seven segment displays are designed for appleications 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 device 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 GaP substrate. The yellow, red orange and high efficiency red series devices utilize LED chips which are made from GaAsP on a transparent GaP substrate. Notes:All dimensions are in millimeters (inches). Tolerance: 0.25mm (0.01") unless otherwise noted.
