| GaAlAs T-1 3/4 Modified 5 Infrared Emitting Diode LTE-2871/LTE-2871C Features Selected to specific on-line intensity and radiant intensity ranges. Low cost plastic end looking package. T-13/4modified package. The LTE-2871 series are made with Gallium Aluminum Arsenide window layer on Gallium Arsenide infrared emitting diodes. Package Dimensions Description The LTE-2871 series are high intensity Gallium Aluminum Arsenide infrared emitting diodes mounted in clear plastic end looking packages. The LTE-2871 series provides a broad range of intensity selection. Suffix C-smoke color lens. Notes: 1. All dimensions are in millimeters (inches). 2. Tolerance is 0.25mm (.010") unless otherwise noted. 3. Protruded resin under flange is 1.5mm (.059") max. 4. Lead spacing is measured where the leads emerge from the package. 5. Specifications are subject to change without notice.
