Product Overview
The 5mm Diffused Blue LED is an industry-standard T-1 3/4 through-hole optoelectronic indicator engineered for uniform light distribution and soft visual signaling. Featuring an advanced frosted epoxy resin lens, this light-emitting diode homogenizes light output to eliminate harsh hot spots and high-intensity focal beams typical of clear-water lenses. It provides a wide 60-degree viewing angle, ensuring comfortable direct-view visibility across interface panels, control decks, and electronic instrumentation.
Technical Specifications and Electrical Characteristics
Built on InGaN (Indium Gallium Nitride) semiconductor technology, this solid-state light source operates at a typical forward voltage (VF) of 3.0V to 3.2V under a standard nominal forward current (IF) of 20mA. It emits a vibrant, monochromatic blue spectrum with a peak dominant wavelength between 465nm and 470nm. With a luminous intensity rating optimized for soft indicators (typically 300 mcd to 500 mcd at 20mA), it avoids eye strain in low-light environments. The standard 2.54mm (0.1 inch) lead pitch with anodized silver-plated copper leads facilitates immediate integration into breadboards, prototyping perfboards, and standard automated DIP soldering assembly lines.
Thermal Management and Circuit Integration
For optimal reliability and maximum lifespan, a current-limiting resistor must be placed in series with the LED when connected to standard logic levels such as 5V or 3.3V power rails. Operating at a maximum reverse voltage (VR) of 5V, this component exhibits low power dissipation (~65mW) and robust thermal performance within an operating temperature range of -40 degrees C to +85 degrees C. The long anode lead and shorter cathode lead with a flat edge on the epoxy flange allow quick, error-free polarity identification during manual assembly.
Application Use-Cases and Prototyping
This versatile optoelectronic component is ideal for microcontroller status indicators in platforms like Arduino, ESP32, and Raspberry Pi. It is extensively utilized in audio equipment, DIY synthesizer panels, modular rack systems, custom user interfaces, network router activity lights, automotive interior accents, and educational STEM hardware kits where clear, non-glaring status feedback is mandatory.
