A 3mm LED is a small, round light-emitting diode with a 3mm lens diameter, commonly used for status indicators, custom electronics, and tight spaces. It typically operates at a forward voltage of 1.9V to 2.6V and a maximum forward current of 30mA (recommended 20mA), requiring a current-limiting resistor when used with higher supply voltages.

Diameter: 3mm
Forward Voltage (Vf): ~1.9V – 2.6V (varies slightly by color)
Forward Current (If): 20mA typical, 30mA max
Viewing Angle: ~30 to 35 degrees
Lens Types: Diffused (frosted) or water-clear/opaque

Options:
