This material has a melt point of 290-340°C and is suitable for use in the majority of automatic soldering processes. *Material test thickness 1.6mm LEDs 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 151-535-04-26) Other non-standard lead lengths are available on request. Electro-static Discharge (ESD) Build up of electrostatic 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 sensi- tive devices, changes in manufacturing technology and materials used to produce higher intensityproducts 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. We recommend all users of LED based products follow the guidelines of BS 100015. Note: All luminous intensity figures refer to the unmodified discrete LED.
