Dffused 5mm tri-color LEDs with separate red, green and blue LED chips inside! Ultra bright indicator or illuminator, and fun to color-swirl. 90 degree viewing angle. You can plug these into a breadboard diagonally. 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. Each order comes with 10 LEDs. 0.3/7.6mm on each side, square. Sometimes called "Super flux" or "Piranha" Diffused lens, 90 degree viewing angle Red 620 nm wavelength, Green 517 nm, Blue 460 nm Red 1.8-2.2V Forward Voltage, at 20mA current, Green 3.0-3.3V, Blue 3.0-3.3V Red 800 mcd typical brightness, Green 1500 mcd, Blue 700 mcd (3000 mcd total) FD-115TRGB-A2 Datasheet If you need some help using LEDs, please read our Introduction to using LEDs tutorial for any electronics project.
