High Efficiency LED in Ø 3 mm Tinted Diffused Package
DESCRIPTION
The TLHY44K1L2 series 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 this device provides a high on-off
contrast.
The LED is categorized in luminous intensity groups and
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 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.
