Precautions

Cautions:

• Check your connection circuits before turning on the LED.

• 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.
