High Intensity LED in ø 3 mm Clear Package
Color Type Technology Angle of Half Intensity
Red TLHK4900 AlInGaP on GaAs 16
Description
This device has been designed to meet the increasing
demand for AlInGaP technology.
It is housed in a 3 mm clear plastic package. The small
viewing angle of these devices provides a high
brightness.
All LEDs are categorized in luminous intensity groups.
That allows users to assemble LEDs with uniform
appearance.
