Product catalog summary
Overview: The document provides technical specifications and guidelines for the 103 Series PCB Mounting LEDs by Marl International Limited. It includes features, benefits, technical specifications, and design considerations for various LED models.
Features and Benefits:
  • 3mm right angle PCB with diffused LED for wide viewing angle.
  • Standard intensity LED with lead cropping options.
  • Available in various colors and voltages, conforming to UL94 V-0 flammability rating.
  • Reverse polarity options to save board space and assembly time.
Technical Specifications:
  • LEDs available in red, yellow, green, and bi-color options with typical voltages ranging from 1.7V to 5.6V.
  • Operating temperature range: -40°C to +85°C, with some models up to +70°C.
  • LEDs with built-in resistors for 5-6V products; others require current limiting.
Design Considerations:
  • LED polarity is indicated in diagrams; reverse polarity options available.
  • Bi-color LEDs require supply reversal for color change.
  • Lead cropping available in standard lengths of 3mm and 5mm.
  • Electro-static discharge (ESD) precautions are essential during handling and assembly.
  • Forward voltage/current values depend on ambient temperature; operation outside specified ranges is not recommended.
Material and Safety:
  • Housing material is Nylon6,6 PA66 FR(30), offering UL94 V-0 flame retardancy and suitable for automatic soldering processes.
Graphs: The document includes de-rating graphs showing the relationship between ambient temperature and forward current for different LED colors.

103 SERIES PCB MOUNTING LED HOUSING MATERIAL Nylon6,6 PA66 FR(30) This material offers UL94 V-0 flame retardancy. This material has a melting point of 263°C and is suitable for use in the majority of automatic soldering processes. Green 314 LED Forward Current If (mA) DE-RATING GRAPHS 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,...
