3mm and 5mm LEDs are small, energy-efficient light-emitting diodes commonly used in various electronic and lighting applications. The 3mm LED is more compact and often used for smaller projects, indicators, and displays, while the 5mm LED is slightly larger and generally provides a brighter light output, making it suitable for tasks like larger displays, signage, and automotive applications. Both sizes come in a range of colors, including white, yellow, red, green, and blue, and can be easily integrated into circuits for visual indicators or decorative lighting.
Each LED is designed for low power consumption, operating at a forward voltage of 1.8 V-3.2 V with a current rating of 10-20 mA. The through-hole design with long leads ensures easy soldering and compatibility with breadboards and PCBs.
This assortment is perfect for makers, students, and professionals looking for a versatile, high-quality LED kit for various electronic applications.
