Ultimate LED Current Limiting Resistor Calculator

If you need to calculate the value of a current limiting resistor to protect a Light Emittiing Diode (LED) then take a look at our LED Current Limiting Resistor Calculator.

As well as the theoretical resistance value it will also suggest suitable values that are actually available to buy. These suggested or 'preferred' values are calculated for 5%, 10% and 20% tolerance resistors.


As if that wasn't enough we also provide a chart showing resistor colour codes so you can quickly determine which resistors to choose for your LED circuit.
