This LED calculator will help you calculate the resistor values you will need when designing a series/parallel LED array circuit.
What current limiting resistor value should you use if you have one LED and want to power it with a supply voltage of Vs = 3.8V? To calculate the current limiting resistor, you first need to look in the datasheet (always RTFM first!) for the LED's recommended forward voltage and forward current specifications.
This calculator can help you determine the appropriate resistor value for a LED forward voltage drop and power supply. The resistor is used to limit the amount of current into the diode.
With this online tool, you can easily calculate the current-limiting resistor for one or more LEDs, both in series and in parallel. Simply input the number of LEDs, the supply voltage, LED forward voltage, and LED current.
A current limiting resistor helps mitigate the effect of voltage increases by virtue of its linear IV curve. Additionally, resistors behave oppositely from LEDs in relation to its temperature - as temperature increases, resistance also increases.
Our LED calculator will help you determine the value of the current limiting series resistor when driving a single or an array of low-current LEDs. To get started, input the required values and hit the "Calculate" button.
This calculator will assist you in determining the optimal value of the series dropping resistor to limit the current through your LED. Just input the indicated values and press the “Calculate” button.
