Fixed inductors are electrical components used to store electrical energy in the form of a magnetic field. The 79F120K inductor is a high-powered, high-frequency unit with a variety of applications, ranging from radio frequency (RF) power supplies to audio equipment. In this article, we will discuss the 79F120K application field and working principle.

79F120K Application Field

The 79F120K inductor is a wide-bandwidth component capable of operating up to 400MHz or higher. Due to its high-power operation capability, it is usually employed in RF applications, including RF transmitters and receivers, radio broadcast, RF amplifiers, and antenna switching systems. Furthermore, it can also be used in audio applications, such as radio amplifiers, audio step-up transformers, and audio amplifiers.

79F120K Working Principle

The 79F120K inductor works by converting electrical energy into magnetic energy. The electrical current passing through the windings of the inductor creates a magnetic field, which in turn induces a counter electromotive force (EMF). This EMF produces an opposing force that opposes the flow of current, thus limiting the application of current through the inductor. Since the magnitude of the current applied to the inductor is directly proportional to the magnitude of the magnetic field created, the 79F120K inductor is also known as a “wideband” inductor as the generated magnetic field is fairly wide in frequency.

Apart from the magnetic field, the 79F120K inductor also incorporates ferrite core material into its construction in order to enhance the inductance. This material helps to concentrate the magnetic field lines produced by the current within the inductor, thus increasing the inductance of the inductor. Moreover, the core material also helps to increase the inductor’s impedance, allowing it to operate at higher frequencies while dissipating less power.

Overall, the 79F120K inductor is a high-powered, high-frequency component that is employed in various RF and audio applications. With its wideband operation and high inductance, the 79F120K inductor is a popular choice for applications in radio broadcast, RF amplifiers, and audio amplifiers.
