5mm Triple Output LED RGB - Common cathode (20 PCs)

The illustration above shows a 5mm RGB (Red, Green, Blue) LED with four pins. It has a triple output, one for each color, and a common cathode. This LED is super versatile! You can use it as three status indicators or use pulse width modulation to mix all three colors and create unique hues. This pack comes with 20 units of 5mm LED RGB with a common cathode. The chip material is InGaN, and the lens type is water clear. For the red light, the forward voltage is 1.8 - 2.5V, the dominant wavelength is 615 - 645nm, the luminous intensity is 200 - 600mcd, and the viewing angle is ±60 degrees. For the green light, the forward voltage is 2.8 - 4.0V, the dominant wavelength is 455 - 480nm, the luminous intensity is 200 - 400mcd, and the viewing angle is ±60 degrees. For the blue light, the forward voltage is 2.8 - 4.0V, the dominant wavelength is 500 - 540nm, the luminous intensity is 300 - 800mcd, and the viewing angle is ±60 degrees. When the forward current (IF) is 20mA and the reverse voltage (VR) is 5V, the forward voltage for RGB is (2.0, 3.2, 3.2) V, and the luminosity for RGB is (800, 400, 900) mcd.

Using these 5mm RGB LEDs is easy. First, identify the common cathode pin. Then, connect the other three pins to the appropriate power sources for red, green, and blue. You can use them as status indicators by simply powering on the corresponding color. If you want to create mixed colors, use pulse width modulation. To do this, adjust the power supply to each color pin to control the intensity of each color. When handling these LEDs, be careful not to bend the pins too much as it may damage the internal connections. Also, make sure to keep the forward current at 20mA and the reverse voltage at 5V to avoid overheating or damaging the LEDs. For maintenance, just keep them clean and dry. If you notice any dimness or abnormal colors, check the connections and the power supply. That's it! Enjoy using these versatile LEDs to add some color to your projects.
