Circuit Design Notes:

Protective current-limiting resistors may be necessary for operating LEDs within the specified range.
LEDs mounted in parallel should each have their own current-limiting resistor.
The driving circuit should protect the LED against reverse voltages and transient voltage spikes.
Precautionary Notes:

The information provided is intended for technical reference and is subject to change without notice.
Customers should refer to the latest datasheet for updated specifications before production usage.
