The Yellow 3mm LED is a compact through-hole indicator LED designed for electronic circuits, signal indication, and prototyping applications. It features a diffused yellow lens that provides soft and uniform light output with wide visibility. Operating at a forward voltage of 5V DC and up to 20mA current, it delivers stable illumination and reliable performance in breadboards, Arduino projects, educational kits, and embedded systems. The standard 3mm package allows easy integration into PCB assemblies and compact electronic designs.
