High Efficiency LED in Ø 3 mm Tinted Diffused Package
DESCRIPTION
The TLHG44K1L2 was developed for standard applications
like general indicating and lighting purposes.
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 LEDs are categorized in luminous intensity groups. The
color is categorized additionally in wavelength 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 reel (there will be no mixing of two groups on
each reel). 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 reel.
In order to ensure availability, single wavelength groups will not
be orderable.
Note
• Wavelengths are tested at a current pulse duration of 25 ms.
