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.

Resistor chart for led. As led forward voltages. This led calculator will help you design your led array and choose the best current limiting resistors values. 30 35 volts led current.

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. 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. 2 volts blue and white.

If you require assistance in determining the color code for a resistor value specified please be sure to visit our resistor color code calculation information page. Current limiting resistor calculator for leds. Current limiting resistor calculator for leds.

The guru single led series leds parallel ledsguru. Just use the standard resistor values chart to find the nearest highest value available. The blue led has a typical forward voltage drop of 32 v therefore a 5 w resistor is required when using a 33 v supply voltage.

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. Superbright leds can go from 30ma up to several amps. 20ma will work for most regular leds.

However if you are using a 5 v supply voltage then a 90 w resistor is needed. Optionally calculate the resistor to accommodate multiple leds connected in series.
