Fixed inductors are components where the inductance is pre-set and does not change with a variation of applied current or voltage. They are one of the commonly used electronic components and are found in a great number of devices, including television, radio, telephones, and most other consumer electronic products. 70F472AF is a type of fixed inductors which has a wide range of application fields and working principles.

Application Field

The 70F472AF fixed inductors are generally used in power conversion and filtering applications. They are often used in switching power supplies due to their high reliability, high efficiency, low cost and low electromagnetic interference (EMI). This type of inductor can also be used in breakers and high power electronic circuits. Additionally, they are widely utilized for filtering in communication and industrial control systems, and for voltage regulation in the field of electrical and electronics engineering.

Working Principle

A fixed inductor is composed of an electric conductor, such as a wire, that has been wound around one or more cores. The core can be made from a variety of materials, including ferrite, iron, powdered iron, mu-metal, film, or toroidal. This electric conductor is both the source of the inductance and the source of the inductor\'s resistance. The inductor will create a magnetic field when current flows through the electric conductor, which is called inductance.

The inductance is directly proportional to the number of times the wire is wound around the core, the size of the core, and the material of the core. Additionally, the inductance can be varied with an abnormal variation of air gap, temperature, and applied frequency. When used as a filter, the inductor will reduce the transfer of high-frequency signals and allow only low-frequency signals to pass from one side to another. When used in incorporating circuits, the inductor can increase output voltage and power.

70F472AF fixed inductors have the unique feature of self-reset and thus can be used in various scenarios where there is a need for fixed inductance and resetting. The self-resetting feature of 70F472AF means it offers better immunity to transient over +85 degree C, making them a popular choice for applications with high temperature control.

Conclusion

The 70F472AF fixed inductors have a wide range of applications and working principles. They are generally used in power conversion and filtering applications. The inductance of a fixed inductor is directly proportional to the number of times the wire is wound around the core, the size of the core, and the material of the core, and can be varied with an abnormal variation of air gap, temperature, and applied frequency. Additionally, the self-resetting feature of 70F472AF inductors makes them a popular choice for applications with high temperature control.
