Led resistor online calculator. Led resistor calculator calculate the resistor to use in a circuit with an led by entering the supply voltage forward voltage and forward current below. This calculator determines that for you. Led series resistor calculator.

Note that this method is not recommended for high current leds which need a more reliable switching current regulator. Thus limiting the current through the led with the use of a series resistor is a common and simple practice. This calculator will help you determine the value of the resistor to add in series with the led to limit the current.

For the protection or limiting the current we simply use a resistor in series with it. This led resistor calculator will help you to pick up a right value of resistor for the led in your led circuit you just have to input the values of source voltage v s led forward current i f and led forward voltage v f. This led calculator will help you design your led array and choose the best current limiting resistors values.

Led series current limiting resistor calculator useful when designing circuits with a single led or seriesparallel led arrays for both the common small current 20ma leds and the more expensive high power leds with currents up to a few amperes. The current through the circuit is constant so i led is also the current through the resistor. The online calculator below allows for the automatic calculation of the necessary current limiting resistor to maximize the useful life of an led.

V led is the voltage drop across the led measured in volts v i led is the current through the led measured in amperes ampsa and. The led calculator will display the resistance value draw a small schematic and show you the color code of the nearest lower and higher. The guru single led series leds parallel ledsguru.

The wizard will help you pick the resistors make the connections for any number of leds. R is the resistance measured in ohms w. Superbright leds can go from 30ma up to several amps.

Current limiting resistor value. 20ma will work for most regular leds. To get started input the required fields below and hit the design circuit.

30 35 volts led current. The calculator will display dropping resistor value along with power rating for either running a single led or multiple leds in series from a power source. Current limiting resistor calculator for leds.

When you select a resistor for this purpose choose a device with a power rating between 2 and 10 times the value calculated below in order to avoid excessive. Optionally calculate the resistor to accommodate multiple leds connected in series. Use this tool to calculate the resistance required to drive one or more series connected leds from a voltage source at a specified current level.

As led forward voltages.
