High Efficiency LED, Ø 3 mm Tinted Total Diffused Package
DESCRIPTION
The TLHA44.. series was developed for applications
which need a very wide radiation angle like
backlighting, general indicating and lighting purposes.
It is housed in a 3 mm tinted total diffused plastic
package. The wide viewing angle of these devices
provides a high on-off contrast.
All LEDs are categorized in luminous intensity groups.
FEATURES
• AlInGaP technology
• Standard Ø 3 (T-1) package
• Small mechanical tolerances
• Suitable for DC and high peak current
• Wide viewing angle
• Very high intensity
• Luminous intensity categorized
• ESD-withstand voltage: up to 2 kV HBM
according to JESD22-A114-B
• Compliant to RoHS Directive 2002/95/EC and in
accordance to WEEE 2002/96/EC
APPLICATIONS
• Status lights
• Off/on indicator
• Background illumination
• Readout lights
• Maintenance lights
• Legend light
PRODUCT GROUP AND PACKAGE DATA
• Product group: LED
• Package: 3 mm
• Product series: standard

Note:
1) In one packing unit IVmin./IVmax. ≤ 0.5
Note:
Luminous intensity is tested at a current pulse duration of 25 ms and
an accuracy of ± 11 %.
These 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.
