LED DİRENÇ HESAPLAMA

All LEDs require current limiting, without a current limiting mechanism the LED will usually burn out in under a second. Adding a simple resistor is the easiest way to limit the current. Use the calculator below to find out the value of resistor you require.

For example if you are wanting to power one of our_blank">red LEDs in an automotive application you would see that the typical forward voltage is 2.0 Volts and the maximum continuous forward current is 30mA. Therefore you would enter 14.5, 2.0 and 30 into the Single LED calculation box. After calculating you get 470ohm 1 watt as the result. Here is a that allows you to enter a resistor value and generate the corresponding color code.

Note: For automotive applications use the actual system voltage, not 12 Volts. Most 12 Volt system actually operate at around 14.5 Volts.

Resistor values are in Ohms (1K = 1000) - Capacitor values are in Microfarads (1uF = 1)

NOTE: The leakage currents of electrolytic capacitors will affect the actual output results of the timers. To compensate for leakage it is often better to use a higher value capacitor and lower value resistances in the timer circuits.
