Introducing the 3mm through hole LED, a compact and versatile lighting solution that has become increasingly popular in various industries. This article delves into the world of 3mm through hole LEDs, exploring their characteristics, applications, and the technological advancements that have made them a staple in the lighting industry.

What is a 3mm Through Hole LED?

The 3mm through hole LED is a type of light-emitting diode (LED) that is designed with a hole through its center, allowing it to be mounted on a printed circuit board (PCB) from both sides. This unique feature makes it ideal for applications where a compact, lightweight, and low-profile solution is required. The diameter of the through hole is typically 3mm, which is a standard size that is widely compatible with many PCB designs.

Design and Specifications

3mm through hole LEDs are known for their small size and simple design. They consist of a semiconductor chip encapsulated in a clear or colored epoxy, with a metallic base for electrical connection. The leads of the LED can be either straight or bent, depending on the specific application and PCB layout requirements. In terms of specifications, 3mm through hole LEDs come in a variety of colors, including red, green, blue, yellow, and white. They also have different forward voltages and forward currents, which determine their brightness and power consumption. For example, a red 3mm through hole LED may have a forward voltage of 2.0V and a forward current of 20mA, while a white LED might have a forward voltage of 3.2V and a forward current of 30mA.
