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 plas-
tic 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.
