3mm Through Hole LED: Enhance Your Lighting Solutions!

Introduction

What is a 3mm Through Hole LED?

The 3mm through hole LED, also known as a 3mm SMD LED, is a compact and versatile lighting component widely used in various applications. As the name suggests, this type of LED has a diameter of 3mm and features a through hole design, allowing it to be mounted on a printed circuit board (PCB) from either the top or bottom side. Due to its small size, 3mm through hole LEDs are highly sought after for applications where space is limited, and brightness is required.

In recent years, the demand for 3mm through hole LEDs has surged, driven by the rapid development of the LED industry and the increasing popularity of smart devices. These LEDs are used in a wide range of applications, including consumer electronics, automotive, industrial, and medical fields. This article will provide an in-depth introduction to the 3mm through hole LED, covering its characteristics, applications, and market trends.

Characteristics of 3mm Through Hole LEDs

1. Size: The diameter of a 3mm through hole LED is only 3mm, making it one of the smallest LED packages available. This compact size allows for high-density mounting on PCBs, enabling designers to create space-saving products.

2. Brightness: Despite its small size, a 3mm through hole LED can emit high-intensity light. The brightness of these LEDs is measured in millicandelas (mcd) or lumens (lm), and it can range from 100mcd to 3000mcd or even higher, depending on the specific model and manufacturer.

3. Color: 3mm through hole LEDs are available in a wide range of colors, including red, green, blue, yellow, white, and RGB (red, green, blue) combinations. This color diversity allows designers to create visually appealing and functional products.

4. Forward Voltage: The forward voltage of a 3mm through hole LED is typically between 2.0V and 3.3V, making it compatible with most voltage sources. This flexibility allows designers to use these LEDs in various applications without worrying about compatibility issues.

5. Heat Dissipation: As with other LEDs, 3mm through hole LEDs generate heat when in use. Proper heat dissipation is essential to ensure the longevity and reliability of the product. These LEDs are often mounted on a PCB with thermal vias or a heat sink to facilitate heat dissipation.
