142-150 SERIES

      The 142-150 SERIES (PACK QUANTITY = 50 PIECES) are multi-colour permutations available, product illustrated 148-214-02, 2 to 10 way configurations, reverse polarity options, housing conforms to UL94 V-O flammability ratings, availableand typically available ex-stock, which can be ordered at website: www.marl.co.uk; Email: sales@marl.co.uk, or Telephone +44 (0)1229 582430; Fax: +44 (0)1229 585155.
      Some characteristics of the 142-150 SERIES (Ta = 25°C) are got. A maim kind of materials the series use is polycarbonate. This material offers UL94 V-0 flame retardancy(Material test thickness 1.6mm)and a high impact strength. This material has a melt point of 290-340°C and is suitable for use inthe majority of automatic soldering processes.
      For 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 '+' sig. And Electro-static Discharge (ESD) is built 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 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. We recommend all users of LED based products follow the guidelines of BS 100015.
