Fixed Inductors

Fixed inductors are an important type of electronic components in modern electronic systems. The 7440700068 is a convenient product for applications which need high level of electrical performance with light weight construction.

Application Field

This inductor can be found in a variety of industrial, automation, and high frequency applications. It is suitable for use in power supplies, RF circuits, power amplifiers, and noise suppression. Moreover, it can be used in filtering applications. The extremely low ESR and ESL allow it to be used in demanding high frequency applications. Therefore, it is one of the most popular fixed inductors in the industry.

Working Principle

In simple terms, a fixed inductor works by converting electrical energy into kinetic and electromagnetic energy through the process of induction. This can the understood by using the basic principle of electromagnetism. It states that when electric current flows through a conducting medium, a magnetic field is induced in the surrounding space. When the magnetic circuit is closed, electrical energy is continuously converted to mechanical energy, and then back into electrical energy. The 7440700068 fixed inductor works similarly, by utilizing this magnetic force.

In general, the inductance of a fixed inductor is considerably higher than that of an equivalent wirewound inductor. This is because the inductor has a higher permeability than air and therefore can store more energy in the magnetic field. It is typically made with a spooled inductance core wrapped with enameled magnet wire and can achieve a maximum inductance value of 80NH. Since it has a relatively low resistance, it has the ability to deliver high currents with minimal losses.

The 7440700068 fixed inductor can be used in many different applications, such as, voltage regulation, noise suppression, switching applications, and motor speed control. The availability of various types of cores such as iron, ferrite, and powder metal allow for exacting design requirements. Furthermore, the manufacturer suggests a working frequency up to 1000MHz for optimal performance.

Conclusion

The 7440700068 fixed inductor has many advantages in terms of efficiency, size, and cost. Its compact size and low ESR and ESL allow it to be used in extremely high frequencies with minimal losses. It can also handle a wide range of current and is suitable for a variety of applications. The wide variety of cores and magnet wire make it easy to customize for the best performance possible. The 7440700068 fixed inductor is thus an excellent choice for high performance, high frequency applications.
