RED led 5 mm

The 5mm round diffused red LED is a standard through-hole light-emitting diode widely used in hobbyist and professional electronics. The diffused lens provides a wide, soft viewing angle, making it perfect for status indicators and displays. With a forward voltage of 2.0-2.2V and a recommended forward current of 20mA, this LED is compatible with most microcontroller boards (Arduino, Raspberry Pi, PIC, etc.) when used with an appropriate current-limiting resistor. The luminous intensity of 450-800 mcd ensures good visibility indoors without being overly bright. The 5mm package is durable and easy to mount on breadboards, PCBs, or panels.
