High Intensity LED in Ø 3 mm Tinted Diffused Package
DESCRIPTION
These devices have been designed to meet the
increasing demand for AlInGaP technology general
indicating and lighting purposes.
They are housed in a 3 mm diffused plastic package.
The wide viewing angle of these devices provides a
high brightness.
All packing units are categorized in luminous intensity
groups. That allows users to assemble LEDs with
uniform appearance.

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.
Note:
Wavelengths are tested at a current pulse duration of 25 ms.
