109 series
design considerations
LED Polarity
Anode identification is shown in the dimensional diagram. The long lead of a non cropped unit can also be used to help identify
the anode. For the 2 pin bi-colour units the standard colour configuration is red anode to the ‘+’ sign.
Reverse Polarity
This is offered on all PCB units, with the exception of the 125 series, if requested to help overcome the problem of systems
with reverse polarity connections. Multiple units can also be supplied in reverse polarity but not with mixed polarities. The 2 pin
and 3 pin bi-colours can be supplied in reverse colour configuration.
Lead Cropping
Should lead cropping be required, Marl offer two standard lengths, either by request or by adding one of the following codes to
the end of the part number:-
-24 = 3mm.
-26 = 5mm (e.g 101-205-02-26)
Other non standard lead lengths are available on request.
Bi-Colour
2 pin operation. To achieve the second colour for a 2 pin bi-colour unit, the supply must be reversed, standard colour
configuration for these units is red anode to the ‘+’ sign.
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.
Power De-Rating
The forward voltage/ current value of an LED is dependant 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. Consequently, a recommendation regarding operating voltages and currents is given in order to address
these temperature effects. This recommendation is termed ‘de-rating’. It is usual for forward voltages and currents to be
specified for ambient temperature of 25°C. However, because the values of these qualities vary with temperature, marl should
be contacted if the device is to be operated at a temperature significantly higher than 25°C. Marl accept no liability for any
product that is operated higher than the stated voltage.
