Additional Details

The LTST-C191KRKT-EL requires a current limiting resistor to prevent damage from excessive current. The value of the resistor should be chosen based on the forward voltage and desired current, which can be found in the manufacturer's datasheet. This LED is designed for reflow soldering processes, and the manufacturer's recommended soldering profile should be followed to ensure reliable connections. The LED is typically shipped on tape and reel for automated assembly. Proper ESD precautions should be taken during handling and assembly to prevent damage to the LED. Refer to the Lite-On Inc. datasheet for detailed electrical and optical characteristics, including forward voltage, luminous intensity, and wavelength.
