100 x red LED 3mm
100 x yellow LED 3mm
100 x white LED 3mm
100 x blue LED 3mm
Max. current (continuous) is 20mA, resulting in 2-3V forward voltage, depending on the color. LEDs are operated at constant current, not voltage! It is necessary, to limit the LED forward current with a resistor.
The value of the resistor is easy to calculate following Ohm’s law: R = U / I For example, a red LED with 10mA forward current at 2.2V, on a 12V power supply: U = 12-2.2 = 9.8V I = 0.01A R = 980 Ohm (1K)
