Fixed Inductors: 103-223FS application field and working principle

Fixed inductors can be used in a variety of circuits, but are commonly found in power supplies, circuit protection, and Automatic Test Equipment (ATE). The 103-223FS, a shielded SMD Fixed Inductor, is one of the most common and widely used inductors, designed with many features and benefits over traditional types. This article will discuss the application field and working principle of the 103-223FS.

Application Field

The 103-223FS is primarily used in switch-mode power supplies, low EMI filters, and other general circuit designs. It is also used in Automatic Test Equipment (ATE), such as AC or DC output voltage measurements for ATE systems, and in RFID tag readers. The 103-223FS is also a popular choice for clock circuits on modern computer systems, providing low EMI interference suppression when used.

This inductor can also be used as a part of differential mode filters, as well as in buck or boost DC/DC converter circuits. In a buck circuit, the 103-223FS can be used to reduce current ripple and improve system efficiency. In a boost circuit, the 103-223FS can be used as an energy storage device between the input and output of the circuit. The wide frequency range of the 103-223FS can be used in a variety of applications, including radio frequency, wireless, GPS, and digital communication systems.

Working Principle

The 103-223FS is a shielded SMD Fixed Inductor, with a maximum DC resistance of 178 mΩ and an inductance range of 4.7~220 μH. It has a low electrical field parallel to the core, resulting in low EMI radiation. The high electromagnetic force of the ferrite core allows for higher power dissipation. The housing and shielding of the 103-223FS provides excellent thermal performance and high reliability.

When exposed to AC signals, the 103-223FS creates a magnetic field around the wire, inducing an opposing current through the wire. This opposes the current in the main circuit, creating a stopping force, also known as inductance. This inductance helps to reduce the amplitude of an AC signal, thus providing EMI suppression and power regulation.

The 103-223FS is a very efficient inductor, with a wide operating frequency range of 200 kHz-50 MHz. This allows the inductor to be used in most circuit types, including high frequency switching applications, such as Bluetooth and WiFi. The inductance of the 103-223FS also helps to reduce power dissipation in circuits, resulting in improved efficiency and system performance.

Conclusion

The 103-223FS is a shielded SMD Fixed Inductor, widely used for DC/DC converter circuits, RFID tag readers, and other high frequency switching applications. It has a very low ground resistance and a high operating frequency range of 200 kHz-50MHz. The 103-223FS provides excellent EMI suppression and thermal performance, allowing for improved system efficiency and reliability. The 103-223FS is a great choice for a wide range of circuits, including switch-mode power supplies, ATE systems, and differential mode filters.
