100 pcs yellow LED 3mm clear, tinted
100 pcs yellow LED 3mm clear, tinted. Max. current (continuous) is 20mA, resulting in 2.0-2.1V forward voltage. 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 l
