5mm RGB LED, Common Cathode, Pack of 10
This common cathode RGB LED is ideal for small light up projects or just to add the RGB light to something larger.
This LED requires a protection resistor to regulate the current, for a 5V supply (Arduino) then a 300 Ohm resistor is recommended.
Forward Volt drop Red: 2V
Forward Volt drop Green: 2.75V
Forward Volt drop Blue: 2.8V
Recommended Forward Current: 10mA
