28 wrz 2024 · This calculator finds the series resistor value to be used with an LED and a +12 Volt supply. This resistor limits current into the diode and is required for proper operation. It also provides the power dissipation in the resistor – an important number for resistor selection.
This LED calculator will help you calculate the resistor values you will need when designing a series/parallel LED array circuit.
5 paź 2024 · Use this calculator to determine the appropriate resistor value for your LED circuit. Enter the supply voltage, forward voltage, and forward current to calculate the recommended series resistor.
23 sty 2024 · Our user-friendly calculator helps you determine the resistance needed to power one or more series-connected LEDs from a specified voltage source at a designated current level. The calculation, rooted in Ohm's Law, also accounts for the voltage drop across the LED.
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.
2 gru 2010 · 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. In this example, they are 3.1V and 30mA respectively.
DigiKey's LED series resistor calculator uses supply voltage, forward voltage, and forward current values to help you identify the correct series resistor.
