DESCRIPTION
• Material categorization:
for definitions of compliance please see
www.vishay.com/doc?99912
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.
APPLICATIONS
All packing units are categorized in luminous intensity and
color groups. That allows users to assemble with uniform
appearance.
• Off / on indicator
• Status lights
• Background illumination
• Readout lights
PRODUCT GROUP AND PACKAGE DATA
• Maintenance lights
• Product group: LED
• Legend light
• Package: 3 mm
• Product series: standard
• Angle of half intensity: ± 22°

Note
• Luminous intensity is tested at a current pulse duration of 25 ms and an accuracy of ± 11 %.The above type numbers represent the order
groups which include only a few brightness groups. Only one group will be shipped on each bag (there will be no mixing of two groups on
each bag).
In order to ensure availability, single brightness groups will not be orderable.
In a similar manner for colors where wavelength groups are measured and binned, single wavelength groups will be shipped on any one bag.
In order to ensure availability, single wavelength groups will not be orderable.
