Introduction to Fixed InductorsFixed inductors, also known as fixed-value inductors, are used in almost all kinds of electronic products. Fixed inductors are electronic components that store electrical energy in the form of an electromagnet and return it under certain conditions. In general, it consists of an iron core and a coil wound over it, so that when current passes through the coil, an electromagnetic field will be generated.Fixed inductors are widely used in electronic circuits as part of a variety of different components, and are particularly important in the manufacture and operation of devices such as motors and generators. The primary purpose of a fixed inductor is to increase the voltage of a circuit at certain frequencies. Therefore, the choice of inductor for any given application depends on its ability to provide adequate voltage.In terms of frequency, fixed inductors can usually be separated into two broad categories: low frequency (LF) and high frequency (HF). Low frequency fixed inductors are generally used in audio frequency applications, while high frequency fixed inductors are used in RF (radio frequency) applications. The most common types of fixed inductors in use today are, LFV25T-470K-EF, also referred to as “variable” inductors, and HFV25T-470K-EF, also referred to as “Fixed” inductors.Application Field and Working Principle of LFV25T-470K-EF.The LFV25T-470K-EF fixed inductor, often referred to as a “variable inductor” is a commonly used type of inductor in audio and frequency (AF) applications. It features a relatively small size, high current carrying capacity and adjustable inductance characteristics. The inductance of the core can be adjusted by altering the number of turns of the coil. The maximum inductance of the LFV25T-470K-EF inductor is 470K.The working principle of the LFV25T-470K-EF is based on the principle of mutual inductance. This type of inductor works by creating an interference pattern within the magnetic fields generated by both the primary and secondary coils. This interference pattern causes a coulombic force, which can be measured as an electrical current. The intensity of this current depends on the number of turns of the coil and the inductance of the core.The LFV25T-470K-EF inductor is mainly used in audio crossover-networks, signal amplification devices and microphone preamplifiers. It is also used in speaker crossover networks and for audio equalization tasks. In addition, it is often used in digital filter circuits and in signal processing circuits.Conclusion To conclude, the LFV25T-470K-EF fixed inductor is an important component used in many different types of electronic applications. It is a high-current carrying component with adjustable inductance that makes it suitable for a variety of tasks. It can be used for audio crossover-networks, signal amplification devices, microphone preamplifiers, speaker crossover networks, audio equalization tasks, digital filter circuits and signal processing circuits.
