I. Introduction
Surface Mount Device (SMD) Inductors are a critical component in many electronic devices. This guide aims to provide a comprehensive understanding of SMD Inductors, their applications, and how to choose the right one for your project.
II. Understanding SMD Inductors
A. What is an SMD Inductor?
An SMD Inductor is a type of inductor that is designed to be mounted on the surface of a circuit board. They are typically smaller than their through-hole counterparts and are used in high-frequency applications.
B. How does an SMD Inductor work?
SMD Inductors work by storing energy in a magnetic field when an electric current passes through it. They are used to block or filter high-frequency noise in electronic circuits.
