Features
Package Dimensions
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.
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.
