Introduction to Infrared SMD: A Comprehensive Industry Overview

Infrared SMD: What is it?

Infrared SMD, or Surface Mount Device, refers to a type of electronic component that is mounted directly onto the surface of a printed circuit board (PCB). These devices are commonly used in a wide range of applications, such as consumer electronics, automotive systems, medical devices, and industrial control systems. The key feature of infrared SMD is their ability to emit or detect infrared radiation, which is an electromagnetic wave with a longer wavelength than visible light. Infrared SMD components are designed to operate within the infrared spectrum, which spans from 0.75 to 1000 micrometers. This spectrum is further divided into three sub-bands: near-infrared (NIR), mid-infrared (MIR), and far-infrared (FIR). Each sub-band has its own specific applications and benefits, making infrared SMD a versatile and widely used technology in the electronics industry.
