Additional Details

The LTST-C191HRGYW requires separate current limiting resistors for each color channel to prevent damage. The forward voltage for each color may vary, so it's important to consult the datasheet for accurate resistor values. This LED is typically packaged on tape and reel for automated assembly. Proper soldering techniques, as outlined in the manufacturer's specifications, are crucial for reliable performance. Care should be taken to avoid electrostatic discharge (ESD) during handling and assembly. For detailed electrical and optical characteristics, refer to the official datasheet provided by Lite-On Inc.
