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.
* 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.

DESIGN CONSIDERATIONS
Electro-Static Discharge (ESD)
Build up of electro-static discharge occurs in many situations
involving people moving and handling products.The range
of possible situations is very diverse but voltage levels as
high as several thousand volts can and do arise in many
individual situations. When an operator charged up to these
levels handles a static sensitive device, there is a very
probable likelihood that the device will be irreversibly
damaged. It is essential that precautions are taken at all
stages during manufacture and assembly of these products.
Although LEDs were never considered to be static sensitive
devices, changes in manufacturing technology and
materials used to produce higher intensity products over a
large range of the wavelength spectrum have changed this.
Marl has an approved system of ESD control from goods
in, through production and into final packing and despatch.
Marl recommend all users of LED based products follow the
guidelines of BS 100015.
Voltage, Current and Temperature
The forward voltage / current value of an LED is dependent
upon the ambient temperature of the environment in which
it is operated. Therefore, care must be taken to operate the
LED at the correct voltage / current values, depending upon
the ambient temperature.
Marl should be contacted if the device is to be operated
outside the temperature range specified. Marl accept no
liability for any product that is operated outside the stated
voltage or temperature range.
