Too much abbreviation in SMT technology, this article clarify this abbreviation to for you.
Light-Emitting Diode,LED is a two terminal Electronic Components. Apply enough voltage between two terminal of LED to emitting color. Different material and Manufacture process decide emitting light color and most of electronic characteristic.
LED is a fragile device. Apply Excessive voltage and current to LED would cause burn out. A simple and effective way to prevent burnout is to series a resistor with the correct value. In this article, we will explain how to series resistor for the most used LED display configuration.
