Fixed inductors are important and versatile electrical components that are used mainly for filtering, oscillating, and similar applications. They are divided into two main categories, fixed inductors or Variable inductors. The 70F685AI is a fixed inductor that can be used for numerous applications. It is a low power inductor with a wide frequency range and a low insertion loss. This article will discuss the application field and working principle of the 70F685AI.

Applications

The 70F685AI is primarily used for filtering and emitting interference in communication systems. It can be used to build simple impedance matching circuits, RF filter networks, and similar applications. Other common applications of this inductor include RF power amplifiers, oscillators, and other electronic circuits. It is also ideal for LC filter circuits, resonator circuits, regenerators, and switching circuits.

Working Principle

The 70F685AI utilizes a closed magnetic core with coils to transform and store energy. It is made up of a series of long helical coils wound around a core. Each core change will cause an energy transfer from one coil to the other. The inductor works by creating a changing magnetic field around itself when a current is introduced into one of its coils. This produces an electromotive force (EMF) in the adjacent coil, which is the opposite of the original current. This EMF will cause the current in the second coil to oppose the original current, thus creating an opposing force against it. This is known as the inductance of the inductor.

In addition to its ability to create an EMF, the inductor also serves as a reactive element, meaning that it has the ability to store energy in its core. This is due to the changing magnetic field that it creates, which allows for the energy to be stored in the coils and released when the current in the inductor changes. This makes the 70F685AI ideal for applications such as energy storage, energy transfer, and filtering.

Conclusion

The 70F685AI is a fixed inductor commonly used for numerous applications, primarily for filtering and emitting interference. It utilizes a closed magnetic core with coils to transform and store energy. Its primary applications include RF power amplifiers, oscillators, and similar electronic circuits. It is ideal for LC filter circuits, resonator circuits, regenerators, and switching circuits. Overall, the 70F685AI is an excellent component for filtering and various other applications due to its low insertion loss, wide frequency range, and ability to store energy.
