Introduction

Fixed inductors are electronic components with a wide range of applications. They are used in many electronic products, including audio systems, radios and many other electronic products. In this article, we will discuss the 1025R-58F fixed inductor application field and working principle.

What is a Fixed Inductor?

A fixed inductor is a passive electrical component that stores electrical energy in the form of a magnetic field when an electrical current flows through it. It converts electrical energy into a magnetic field, which is then converted back into electrical energy as it is discharged. A fixed inductor is a two-terminal component made up of two coils of wire wound around a core material, usually ferrite or iron.

1025R-58F Fixed Inductor

The 1025R-58F is a type of fixed inductor. It is a surface mount component with a footprint of 12.7 mm x 5.4 mm. It features an inductance value of 21.5uH, a DC resistance of 0.16 Ohms and a current rating of 7.5 A. The 1025R-58F is designed for use in high-power DC-DC converters.

1025R-58F Application Field

The 1025R-58F is commonly used in DC-DC converters such as notebook computer power adapters, LED lighting, electronic vehicles, and other applications requiring high power dc-dc conversions. It is also used in switching power supplies for consumer electronics, automotive electronics, medical electronics, etc.

1025R-58F Working Principle

When an alternating current is applied to the 1025R-58F, it behaves like a transformer, converting the AC electrical energy into a magnetic field, storing the energy in its cores. As the current changes direction, the magnetic field changes as well, causing the cores to release the stored energy into a new electrical field. The 1025R-58F then continues this process, converting alternating current into a more useable direct current.

Conclusion

The 1025R-58F fixed inductor is a versatile device used in various electronic products. It is used to convert alternating current into a more useable direct current, making it an essential component of modern electronic systems. Its application fields include switching power supplies, DC-DC converters, and wide variety of other consumer and automotive electronics. Understanding the working principle of these devices is essential for designing and building electronic circuits.
