Description
This 3mm yellow LED is a high-brightness, low-power light-emitting diode designed for a wide variety of indicator and illumination applications. With a diffused or water-clear lens option, it emits a vibrant yellow light at a typical wavelength of 585nm to 590nm . It operates at a low forward voltage of 2.0V to 2.2V and consumes only 20mA of current, making it ideal for battery-powered and microcontroller-based projects .
This compact through-hole LED is perfect for status indicators, warning lights, panel displays, signage, DIY electronics, and educational projects . It is easily interfaceable with Arduino, Raspberry Pi, and other 5V or 3.3V logic systems using a suitable current-limiting resistor . The 3mm size offers a narrow viewing angle of 30° to 45°, providing focused and intense light output . With a long lifespan of up to 100,000 hours, this LED is a reliable choice for both hobbyist and professional applications .
