DESCRIPTION
These are general purpose 5mm RGB common cathode (CC) LEDs that have a Diffused lens.
KEY FEATURES OF LED RGB 5MM CC Diffused LENS:
- RGB (Red/Green/Blue) LEDs contained in same package
- Common cathode (CC)
- 5mm diameter
- Lens Appearance: Diffuse
- 20mA max drive current
- Forward voltage drop of 2.1V red and 2.8V for blue and green
These LEDs are diffused; so they’ll appear dimmer, but have a wider viewing angle.
The LED is common cathode (CC) which means that all 3 of the LEDs have their cathodes tied together. The cathode which is the longest lead is connected to ground and the red, green and blue LED pins should be connected to digital or PWM output pins that will be driven active HIGH to light the LEDs.
Calculating LED Resistor Values
These R/G/B LED pins must have series current limiting resistors to prevent damage to the LED or the MCU that is driving them.
They are logic compatible with a max drive current of 20mA and a typical forward voltage drop of 2.1V for the red and 2.8V for the green and blue LEDs.
At an operating voltage of 5V, series voltage dropping resistors of 150Ω for red and 110Ω for blue and green will provide max brightness or larger resistors of around 220- 470Ω can be used to reduce current at a lower brightness.
