Fixed inductors are passive electronic components used in a variety of electrical circuits. The 2727-19F is an example of a fixed inductor specifically designed for high-frequency applications. Its inductance of 1.9 H is suitable for frequencies up to 4.5 GHz and it can withstand pulse currents up to 1.2 A. In this article, we will look at the application field and working principle of this type of inductor.
Application Field
The 2727-19F is an excellent choice for use in applications that require high-frequency performance. It is used in systems such as cellular phones, cordless phones, satellite communications, and video graphics. It is also suitable for use in switching power supplies, switching regulators, and digital filters. These components are ideal for use in automotive applications due to their low-interference level, their ability to provide high-frequency stability, and their ability to reduce switching noise.
Working Principle
The operating principle for a fixed inductor is based on Faraday’s Law of Induction. According to this law, when a current flow is applied to the inductor, it will generate an opposing magnetic field. This magnetic field, in turn, creates an opposing voltage in the coil termed back EMF or counter EMF, usually denoted by the letter E. The amount of the back EMF is directly proportional to the rate of change of the current in the coil, that is, the more the current changes, the greater the magnitude of the counter EMF.
The 2727-19F is designed to limit the flow of electric current in a circuit. This is accomplished by employing a magnetic core around the coil. This core is composed of a ferrite material which acts as an electrical insulator. As current flows through the coil, an opposing magnetic field is built up in the core, which limits the speed of the current.
Another important feature of this inductor is its self-resonant frequency. This is the frequency for which the inductor has the greatest inductive reactance. As the signal frequency moves away from the self-resonant frequency, inductive reactance decreases and eventually, at very high frequencies, capacitive reactance also becomes present. The self-resonant frequency of the 2727-19F is 1.45GHz.
Finally, the 2727-19F also has very low damping. This is a measure of how quickly the magnetic field dissipates and can be used to determine the quality of the inductor. Low damping is desirable as it ensures that the inductor can handle rapid changes in current without significant losses. The 2727-19F has a damping ratio of less than 0.1.
In conclusion, the 2727-19F is an excellent choice for high-frequency circuit designs as it is able to provide an inductance of 1.9 H up to 4.5 GHz. It is suitable for use in a variety of applications, including cell phones, cordless phones, and other wireless systems. It is also suitable for automotive applications due to its ability to reduce switching noise and provide high-frequency stability. Finally, its low-damping ratio ensures that it can withstand rapid current changes without significant losses.
