Observe the LED polarity: LED anode is marked with a RED dot. DO NOT connect the LED to the multimeter! Soldering: • • • • • Do avoid overheating of the LED Do avoid electrostatic discharge (ESD) Do avoid mechanical stress, shock, and vibration Do only use non-corrosive flux Do not apply current to the LED until it has cooled down to room temperature after soldering Static Electricity: LEDs are sensitive to electrostatic discharge (ESD). Precautions against ESD must be taken when handling or operating these LEDs. Surge voltage or electrostatic discharge can result in complete failure of the device. Operation: Do only operate LEDs with a current source. Running these LEDs from a voltage source will result in complete failure of the device. Current of a LED is an exponential function of the voltage across it. Usage of current regulated drive circuits is mandatory. © All Rights Reserved The above specifications are for reference purpose only and subjected to change without prior notice www.roithner-laser.com 3
