NOTES
Intensities (lv) and colour shades of white (X-Y co-ordinates) may vary between LEDs within a batch. Additional LED Colours, Voltage Options and Flying Lead lengths available for semi-
custom projects. Please contact our Sales Team. All LED components are supplied in anti-static packaging.
* Characteristics stated at Ta = 25°C. For operating temperature derating graphs, please refer to sheet 2.
** These are Current models and the voltage shown is Vf at 20mA, not Vopr. Additionally, there is no reverse protection diode in Current models.
