3mm Green LED (Pack of 10)

The 3mm Green LED (Pack of 10) is a compact and energy-efficient light-emitting diode designed for use in a wide range of electronic circuits and embedded system applications. It produces a bright green light when powered and is commonly used as a power indicator, status indicator, signal light, and visual output device in electronic projects. Featuring a 3 mm round through-hole (DIP) package, this LED is easy to mount on breadboards and printed circuit boards (PCBs), making it suitable for students, hobbyists, and professional engineers.

The 3mm Green LED operates on the principle of electroluminescence, where light is emitted when an electric current passes through a semiconductor junction. It typically operates with a forward voltage of 2.0 V to 2.2 V and a forward current of approximately 20 mA. To ensure safe operation and prevent damage, a current-limiting resistor should always be connected in series with the LED. The longer lead represents the anode (positive terminal), while the shorter lead and the flat edge on the LED body indicate the cathode (negative terminal).

This LED provides bright and clear green illumination with low power consumption and minimal heat generation, making it highly efficient for continuous operation. It offers a long operational life of more than 50,000 hours, fast switching speed, and reliable performance under normal operating conditions. The compact 3 mm size makes it ideal for applications where space is limited while still providing excellent visibility.

The 3mm Green LED is compatible with popular microcontroller platforms such as Arduino, Raspberry Pi, ESP32, ESP8266, PIC, AVR, and other embedded development boards. It is widely used in robotics, IoT devices, automation systems, sensor circuits, educational kits, prototype development, electronic instruments, and DIY electronics projects. It is also commonly used in consumer electronics, communication devices, control panels, and industrial equipment for visual indication.

The Pack of 10 provides multiple LEDs for prototyping, circuit testing, classroom experiments, repairs, and electronic product development. Its combination of low power consumption, durability, compact size, and ease of use makes the 3mm Green LED an essential component for engineers, students, makers, and electronics enthusiasts. Whether used as an indicator light or for decorative and signaling purposes, it delivers reliable and consistent performance across a wide variety of electronic applications.
