The 5mm White LED (Light Emitting Diode) is a compact and energy-efficient electronic component widely used in DIY electronics, Arduino projects, robotics, and indicator applications. With its standard 5 mm round package, it can be easily inserted into breadboards or soldered onto PCBs, making it suitable for both beginners and professionals.
This LED emits a bright white light that is ideal for status indicators, display backlighting, decorative lighting, and electronic circuits. It typically operates at a forward voltage of around 3.0 V to 3.4 V with a recommended forward current of about 20 mA, so a current-limiting resistor should always be used in series to protect the LED.
