Fixed Inductors: 105R-103F Application Field and Working Principle

Fixed inductors, also known as chokes, are important components used in many electronic circuits. This type of inductor has a fixed magnetic core, and a coil wrapped around the core. The most common type of fixed inductor, the 105R-103F, is a specialized type of throughhole component with a ferrite core that is used mostly in analog applications such as radio frequency (RF) filtering and tuning.

Description of 105R-103F

The 105R-103F inductor is a through-hole component with a ferrite core and a coil wrapped around it. It consists of a ferrite core around which a coil of copper wire is wound. The 105R-103F has a very high inductance rating of up to 10,000uH, depending on the configuration. It is a very cost-effective component with a wide range of applications and is available in a variety of sizes and configurations. In addition, the core is magnetically shielded, making it suitable for use in high-frequency, sensitive applications.

Applications of 105R-103F

The 105R-103F inductor has a wide range of applications in analog applications such as RF filtering and tuning. The most common application is for choke filtering, where it is used to reduce high-frequency noise from digital or analog signals. Additionally, it can be used to block or reduce AC line noise from audio or video signals, as well as to provide impedance matching in communications systems. The 105R-103F is also found in many consumer electronics, such as televisions and radios.

Working Principle of 105R-103F

The working principle of the 105R-103F inductor is based on the magnetic field produced by the coil winding around the ferrite core. When an alternating current (AC) passes through the coil, a magnetic field is created, and this field induces a voltage in the coil. As the frequency of the alternating current increases, the voltage induced in the coil increases, resulting in a low impedance path for AC signals. The higher the frequency of the AC signals, the lower the impedance. This makes the 105R-103F ideal for applications requiring high frequency filtering or tuning.

Advantages of 105R-103F

The 105R-103F has a number of advantages over other types of inductors. For one, it is a very cost effective component, with a wide range of applications and configurations. Additionally, it has a high inductance rating and is magnetically shielded for use in sensitive applications. Lastly, its low impedance makes it ideal for use in high frequency filter and tuning applications.

Conclusion

The 105R-103F is a specialized type of throughhole fixed inductor with a ferrite core and a coil wrapped around it. It is used mainly in analog applications such as RF filtering and tuning, and is found in many consumer electronics devices. The working principle of this inductor is based on the magnetic field produced by the coil winding around the ferrite core, which induces a voltage in the coil. Overall, the 105R-103F is a very cost effective component with a wide range of applications and configurations, making it a useful component for many different applications.
