DigiKey's LED series resistor calculator uses supply voltage, forward voltage, and forward current values to help you identify the correct series resistor.
This calculator will help you determine the value of the resistor to add in series with the LEDs to limit the current. Just input the indicated values and press the "Calculate" button. As a bonus, it will also calculate the power consumed by each LED.
Calculate resistor values for LEDs using this simple calculator. Enter any three known values and press Calculate to solve for the others.
Calculation of a current limiting resistor for one or more LEDs connected in series. This calculator is ideal when you have one or more consecutive LEDs and you need to calculate which resistance resistor needs to be connected to the circuit.
When calculating the resistor size that you need to use, you need to find your source voltage, the forward voltage of the LED (basically, at which point the LED starts conducting), and then how much current you want it to conduct.
Calculate the resistor to use in a circuit with an LED by entering the supply voltage, forward voltage, and forward current below. Optionally calculate the resistor to accommodate multiple LEDs connected in series.
