Notes:

1. Don't cause stress to the LEDs while it is exposed to high temperature.

2. The maximum number of reflow soldering passes is 2 times.

3. Reflow soldering is recommended. Other soldering methods are not recommended as they might

cause damage to the product.

CIRCUIT DESIGN NOTES

1. Protective current-limiting resistors may be necessary to operate the LEDs within the specified range.

2. LEDs mounted in parallel should each be placed in series with its own current-limiting resistor.

3. The driving circuit should be designed to protect the LED against reverse

voltages and transient voltage spikes when the circuit is powered up

or shut down.

4. The safe operating current should be chosen after considering the

maximum ambient temperature of the operating environment.

5. Prolonged reverse bias should be avoided, as it could cause metal

migration, leading to an increase in leakage current or causing

a short circuit.
