Introduction to 3mm Light Emitting Diodes

3mm light emitting diodes are a type of semiconductor devices that emit light when an electric current passes through them. They are known for their small size, high brightness, low power consumption, and long lifespan. The 3mm LED is a member of the SMD (Surface Mount Device) family, which includes various sizes ranging from 0603 to 1206. The 3mm size is particularly popular due to its versatility and ease of integration into compact electronic devices.

Evolution of 3mm LEDs

The history of light emitting diodes dates back to the early 20th century, but it was not until the 1960s that LEDs began to gain commercial attention. The first practical LED was developed by Nick Holonyak Jr. at General Electric in 1962. Over the years, advancements in semiconductor technology have led to the miniaturization of LEDs, resulting in the creation of the 3mm LED.
