Clear 5mm tri-color LEDs with separate red, green and blue LED chips inside! Nice bright indicator or illuminator, and fun to color-swirl. 80 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. 0.3/7.6mm on each side, square. Sometimes called 'Super flux' or 'Piranha' Clear lens, 80 degree viewing angle Red 630 nm wavelength, Green 525 nm, Blue 470 nm Red 2.1-2.5V Forward Voltage, at 20mA current, Green 3.8-4.5V, Blue 3.8-4.5V Red 400 mcd typical brightness, Green 1200 mcd, Blue 400 mcd (2000 mcd total) BL-FL7680RGBC Datasheet If you need some help using LEDs, please read our Introduction to using LEDs tutorial for any electronics project.
