Fixed Inductors

Fixed inductors are components that store energy in a magnetic field. They are also known as chokes, coils or reactors, and are widely used in different applications, such as in filter circuits, power supplies, and motor control circuits. A fixed inductor, such as the 79FR56M-RC, is designed to maintain a constant current regardless of how its voltage or frequency changes in time. This type of inductor has many advantages over other types of inductors, including its low cost and long lifetime, and it is often found in consumer electronics and industrial equipment.

79FR56M-RC Application Field and Working Principle

The 79FR56M-RC fixed inductor is mainly used in consumer electronics such as DVD players, audio systems, and TVs. It can also be used in appliances such as air conditioners, refrigerators, washing machines, and electric motors. The 79FR56M-RC is a small, low-profile inductor with an inductance rating of 56 mH +/- 20%. It is designed to be used in switching power supplies as a noise filter.

As a fixed inductor, the 79FR56M-RC relies on magnetic fields to store energy. It comprises an inductor core, wrapped in aluminum wire or other conducting material, with copper leads coming off of it. When a current is applied to the 79FR56M-RC, it creates an electromagnetic field in the core and interacts with the current, which causes a voltage drop, creating a counter-electromotive force, or \'back EMF\'. This back EMF reduces the amount of current entering the circuit, thus reducing the amount of power it consumes, making it an energy-efficient device. The 79FR56M-RC is also designed to maintain a constant current when the voltage and frequency of the current changes, thus providing a reliable and stable source of energy.

The 79FR56M-RC fixed inductor is an exceptionally versatile component as it can be used in both AC and DC applications. It is often used in power supplies to filter out noise that can interfere with other components, such as capacitors and integrated circuits. It is also used in motor control circuits, where it allows a steady current to be maintained, avoiding spikes in current that can damage motors and other components. The 79FR56M-RC can also be used in filter circuits as an alternative to an inductor-capacitor combination.

In summary, the 79FR56M-RC fixed inductor is a versatile component with many applications in consumer electronics, industrial, and motor control circuits. It is an efficient device that uses magnetic fields to store energy, and it maintains a constant current regardless of how the voltage or frequency of the current changes in time.
