3mm

3mm LEDs offer a compact, reliable way to add visual indicators and illumination to electronics projects where space is limited. This category includes 3mm through-hole LEDs in a range of colors and brightness levels, making them ideal for status indicators, control panels, prototypes, and educational circuits.

Used by makers, students, educators, and engineers alike, 3mm LEDs are easy to integrate into breadboards, PCBs, robotics projects, and embedded systems. Their smaller form factor makes them well suited for compact designs while still providing clear, efficient light output.
