Instructions:

1. Mounting:

   • Ensure the LED is mounted on a suitable PCB with proper thermal management.
   • Use appropriate soldering techniques to avoid damage from excessive heat.

2. Electrical Connections:

   • Connect the anode (longer lead) to the positive supply and the cathode (shorter lead) to the ground.
   • Use a current-limiting resistor to prevent exceeding the maximum forward current.

3. Power Supply:

   • Ensure the power supply voltage is within the specified forward voltage range to avoid damage or reduced lifespan.

4. Pulse Operation:

   • For pulse operation, ensure the peak forward current does not exceed 100 mA for pulse widths ≤ 1 ms and duty cycles ≤ 1/10.

5. Thermal Management:

   • Keep the operating temperature within the specified range to ensure reliable performance.
   • If operating in high-temperature environments, consider additional cooling methods such as heatsinks.

6. Storage:

   • Store the LED in a dry, cool place within the specified storage temperature range to prevent degradation.

7. Handling:

   • Handle the LED with care to avoid mechanical damage.
   • Use ESD (Electrostatic Discharge) protection when handling to prevent damage from static electricity.

8. Optical Characteristics:

   • The viewing angle is typically 120°, which means the LED will emit light in a wide angle. Position the LED accordingly for optimal visibility.
