41. RGB LED Selection

Aarav is designing a small embedded status panel and wants to show different system states using a single RGB LED.

The LED should show red for fault, green for normal operation, and blue for communication activity.

To save board space, he decides to use a common cathode, 4-pin, 4-SMD package RGB LED.

Help him select a suitable RGB LED from DigiKey.

Make sure it matches the required package, pin configuration, and works reliably in industrial temperatures.
