LED - RGB Diffused Common Cathode (100 pack)

We all know that you can never get too many LEDs, especially RGB LEDs! Don't worry, we've got you covered. This is a pack of 100. Buy in bulk - save a ton!

These LEDs are diffused; so they'll appear dimmer, but have a wider viewing angle.

  • 100 diffused RGB LEDs
  • Standard size - T1 3/4 5mm
  • Four legs, common cathode
  • Forward Voltage (RGB): (2.0, 3.2, 3.2)V
  • Max Forward Current (RGB): (20, 20, 20)mA
  • Max Luminosity (RGB): (2800, 6500, 1200)mcd

LED - RGB Diffused Common Cathode (100 pack) Product Help and Resources

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

3 Electrical Prototyping

Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.

    There appears to be a fault in the infosheet that is included with this pack of SparkFun diffused LED's: the example circuitry with AA battery four pack has the drawing of the LED mirrored. The 'flat side' is now opposite of where it should be and the long pin, that should be the cathode, is now denoted 'G+'. The whole LED drawing should be mirrored over the horizontal axis to correct this error. Also, compared to the datasheet linked on this page ' R+' en ' B+' seem to be swapped.

      That link is for common anode LEDs, instead of these common cathode LEDs.
      There's an clearer explanation of what this means on the Arduino forum..
      It's not a huge thing, but there's definitely a difference. Working with anode LEDs will mean some counter-intuitive coding, and possibly a significant amount of time spent inverting values after copying/pasting existing code.

        Oh yah, didn't see that. (and yah i know what a common anode and cathode it btw) lol but thanks for pointing that out
