5mm through-hole LED, also known as a 5mm THT LED, is a compact and versatile lighting component widely used in various applications. These LEDs are designed with a through-hole mounting system, making them easy to install in PCBs (Printed Circuit Boards) and other electronic devices. This article delves into the details of 5mm through-hole LEDs, their applications, advantages, and the industry trends surrounding them.

Introduction to 5mm Through-Hole LEDs

5mm through-hole LEDs are a type of LED that features a diameter of 5mm. The term "through-hole" refers to the mounting method where the LED's leads are inserted through the PCB holes and then soldered on the other side. This design allows for easy assembly and replacement, making it a popular choice for both hobbyists and professional electronics engineers.

Construction and Features

5mm through-hole LEDs are typically made of a sapphire or glass substrate with a semiconductor layer that emits light when an electric current passes through it. The LED's housing is usually made of plastic, which protects the internal components and provides a smooth, matte finish. The plastic housing also helps to dissipate heat, ensuring the LED operates at optimal temperatures.

These LEDs come in various colors, including red, green, blue, yellow, and white, and can have different brightness levels. The color and brightness are determined by the semiconductor material used in the LED's chip. Additionally, 5mm through-hole LEDs can have a clear or diffused lens, which affects the light distribution and visibility.
