Selection Recommendations
First check the rectangular package outline, lens, lead polarity and available installation space. Then select the color, brightness and current using the PDF for the complete part number. VF and test conditions may differ by color. Design the current-limiting resistor or constant-current driver for the selected model, supply voltage and target operating current. The test current in the datasheet is not the maximum permissible current. Follow the corresponding datasheet and approved process for lead forming, soldering temperature and soldering time.
