Diffused RGB (tri-color) 10mm LED (10 pack) - Common Anode | Adafruit Industries 848
LED Tri-Color Blue/Green/Red 467nm/523nm/623nm 4-Pin
Make some beautiful colors with these diffused 10mm tri-color LED with separate red, green and blue LED chips inside! They make a nice indicator, and fun to color-swirl. We like diffused RGB LEDs because they color mix inside instead of appearing as 3 distinct LEDs. These are Common-Anode type which means you connect one pin to 5V or so and then tie the other three legs to ground through a resistor. We carry and use CA more than CC because multi-LED driver chips (such as the TLC5940/TLC5941) are often designed exclusively for CA and can't be used with Common-Cathode. 10mm diameter Red 623 nm wavelength, Green 523 nm, Blue 467 nm Red 1.8-2.2V Forward Voltage, at 20mA current, Green 3.0-3.4V, Blue 3.0-3.4V 50 degree viewing angle. Red 700 mcd typical brightness, Green 2100 mcd, Blue 900 mcd Datasheet If you need some help using LEDs, please read our Introduction to using LEDs tutorial for any electronics project.
