Fixed Inductors: 82103C Application Field and Working Principle

Inductors are important and crucial components of every electronic system. They are used to store energy in the form of electric current and often found in electronic circuits. Inductors come in a variety of designs for different applications. Fixed inductors, for one, and their applications and working principles are covered in this article.

What are Fixed Inductors?

Fixed inductors are electronic inductance components that have predetermined, or fixed, inductance values. This type of inductor doesn\'t use any physical core material and consists of coils that have no air gaps. The inductance value of such an inductor is equal to the product of the number of turns on the coil and the permeability of the material used to wrap it. Fixed inductors are a type of passive components widely used in various applications.

82103C Fixed Inductor Application Field

The 82103C is a common type of fixed inductor component, also known as an air core inductor. This inductor is made of ferrite chip material and has a cylindrical case. It is mainly used in high frequency circuits for RF related applications such as amplifiers, noise canceling circuits, filters, oscillators, and switches. This type of inductor is a non-resonant device with a linear inductance change in relation to current, making it suitable for certain applications that require a linear response.

82103C Fixed Inductor Working Principle

The working principle of the 82103C is based on Faraday\'s Law of Induction. This law states that the induced electromotive force (emf) created in a conductor by a changing magnetic field is directly proportional to the rate of change of the magnetic flux threading the conductor. In other words, the electromotive force created in an inductor is proportional to the rate at which current is passed through its windings.

The 82103C fixed inductor is a non-resonant device, meaning it doesn\'t react to frequency changes like a resonant inductor would. When a current is passed through it, it creates a magnetic field that stores electromagnetic energy from the current. The magnitude of this energy depends on the number of turns on the coil and the permeability of the material used to wrap it. The magnetic field then gradually changes in strength as the current decreases, releasing the electromagnetic energy stored in it.

Advantages of Fixed Inductors

Fixed inductors have several advantages over variable inductors such as higher reliability, greater bandwidth and efficiency, and improved linearity. They also have simpler construction compared to variable inductors and reduced parts count. Furthermore, they can be used in applications that require high power levels as their small size and low stray magnetic fields make them suitable in such cases.

Conclusion

Fixed inductors, such as the 82103C air core inductor, are important and commonly used components in many electronic circuits. Their working principle is based on Faraday\'s Law of Induction and they offer several advantages over variable inductors, such as higher bandwidth and stability. The 82103C can be used in applications related to high frequency circuits, amplifiers, noise canceling circuits, filters, oscillators, and switches.
