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
current BSI guidelines for protection of electronic devices
from electrostatic phenomena.
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.
