Description

Ultimate 5mm LED Assortment. 500 LEDs in 5 different colors:

100 x green LED 5mm
100 x red LED 5mm
100 x yellow LED 5mm
100 x white LED 5mm
100 x blue LED 5mm

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 (for medium brightness)

For battery operated applications, you should consider a much lower LED current, for example 3-5mA.
