Learn how to calculate the resistor value for LEDs based on forward voltage, current, and supply voltage. Find charts and formulas for different LED colours and voltages.
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.
DigiKey's LED series resistor calculator uses supply voltage, forward voltage, and forward current values to help you identify the correct series resistor.
23 Ιαν 2024 · Use our helpful LED resistor value calculator to determine what resistor value you require for your LED lighting. Discover the right resistor value with our LED resistor value calculator, incorporating the principles of the law of Ohms and the formula of resistance.
LEDs require a current-limiting resistor to operate at the ideal operating point and ensure a long lifespan. Here, you’ll find all the formulas for their calculation. Additionally, you’ll find a simple online calculator to determine the LED current-limiting resistor using your LED parameters.
19 Αυγ 2012 · We’ll use the following formula to determine the resistor value: Resistor = (Battery Voltage – LED voltage) / desired LED current. For a typical white LED that requires 10mA, powered by 12V the values are: (12-3.4)/.010=860 ohms. To use several LEDs in parallel, sum the current values.
