3mm DIP Diffused Blue LED (Pack of 10)

The 3mm DIP Diffused Blue LED (Pack of 10) is a high-quality light-emitting diode designed for electronic circuits, indicator lights, decorative lighting, educational projects, and DIY applications. It features a 3 mm round diffused epoxy lens that emits a soft and evenly distributed blue light, reducing glare and providing wide-angle illumination compared to clear LEDs. The diffused lens enhances light dispersion, making it suitable for applications where uniform brightness is preferred over a focused beam.

This LED operates on the principle of electroluminescence, where light is produced when an electric current passes through the semiconductor junction. It typically has a forward voltage of 3.0 V to 3.3 V and requires a forward current of approximately 20 mA for normal operation. A current-limiting resistor should always be connected in series with the LED to prevent excessive current and ensure reliable performance. 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).

The 3mm Diffused Blue LED is widely used as a power indicator, status indicator, signal indicator, decorative lighting element, and visual output device in electronic circuits. It is compatible with popular development platforms such as Arduino, Raspberry Pi, ESP32, ESP8266, PIC, AVR, and other microcontrollers, making it an excellent choice for students, hobbyists, and professional engineers. The LED can also be used in breadboard prototyping, robotics projects, sensor circuits, IoT applications, and embedded system development.

One of the main advantages of this LED is its low power consumption, long operational life (typically over 50,000 hours), compact size, high reliability, and fast switching speed. The diffused lens provides uniform illumination and improved visibility from multiple viewing angles, making it suitable for both indoor and outdoor electronic applications. Additionally, LEDs generate very little heat compared to conventional light sources, making them energy-efficient and environmentally friendly.

The Pack of 10 offers multiple LEDs for prototyping, replacements, classroom experiments, and electronic projects. These LEDs are ideal for use in engineering laboratories, educational institutions, hobby electronics, product development, and automation systems. Their compact size, ease of use, and dependable performance make the 3mm DIP Diffused Blue LED one of the most commonly used components for visual indication and lighting in modern electronic designs.
