Resistor Components

Variety of resistors for your LED Lighting Needs.
  • The following is the recommended resistor usage for LED circuits using 12VDC @ 20mA
  • Resistors are 1/4 watt unless otherwise indicated
  • It is NOT recommended to wire single LEDs unless you use a 1/2 watt or greater resistor (or else the resistor will overheat and burn)
3.3 volts LEDs (blue, white, green etc.)
1 LED - 470 ohms (1/2 watt)
2 LEDs - 270 ohms
3 LEDs - 120 ohms
4 or more LEDs - Use multiple arrays of LEDs

2.0 volts LEDs (red, amber etc.)

1 LED - 560 ohms (1/2 watt)
2 LEDs - 470 ohms (1/2 watt)
3 LEDs - 330 ohms
4 LEDs - 220 ohms
5 LEDs - 100 ohms
6 or more LEDs - Use multiple arrays of LEDs
