High Intensity LED in Ø 3 mm Tinted Diffused Package
DESCRIPTION
This series has been designed to meet the increasing
demand for AlInGaP technology.
It is housed in a 3 mm tinted, diffused plastic package.
The wide viewing angle of these devices provides a
high brightness across a large field of view.
All packing units are categorized in luminous intensity
and color groups. That allows users to assemble LEDs
with uniform appearance.

Note:
1) In one packing unit IVmin./IVmax. ≤ 0.5
Note:
Luminous intensity is tested at a current pulse duration of 25 ms.
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.
