201 SERIES

      The 201 SERIES is a kind of FILAMENT REPLACEMENT LEDs - T1. Some  design considerations are as follows. First, all devices feature water clear high intensity LEDs as standard. The single chip LED devices have been modified by the removal of the domed portion of the encapsulation (flat-topped) to provide even illumination of switches and annunciators. Second,  filament Replacement LEDs have been specifically designed to meet the primary objective of providing improved reliability.As this product range is suitable for both new-build and retro-fit, (sometimes in very old systems), a wide range of illuminated push button switches and lamp holders can be encountered. Third, 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. Fourth, the forward voltage/current value of an LED is dependant upon the ambient temperature of the environment in which it is operated.
      Next is some technical information about the 201 series. Its Lamp Base Style is Sub-midget FlangeT1 SX3s, its Metric Equivalent is 4 mm,and the Maximum Power Dissipation is 360(mW).
      Here are some features of 201 SERIES . The first one is Direct replacement for T1 Sub Midget Flange SX3s, the second one is Reverse polarity options, the third one is Fits professional and military stylepush buttons, the last one is Centre contact Anode as standard.
      Some notes of 201 SERIES are as follows:First, Intensities (lv) and colour shades of white (x,y co-ordinates) may vary between LEDs within a batch..Second, Products must be derated according to the derating information. Each derating graph refers to specific LEDs. Appropriate LED numbers shown.
