Fixed Inductors

The LQW18AN6N2C0ZD fixed inductor is a type of passive electronic component commonly used in the power supplies of electronic circuits. It consists of a steel core surrounded by a coil of copper or iron wire, usually coated with enamel insulation. The inductor stores energy in the form of a magnetic field when an electric current passes through it. This means that it can be used to regulate the flow of current in a circuit by providing resistance to change in the circuitry.

Fixed inductors are typically used in applications such as power supplies to regulate the flow of current and voltage, suppress spikes in power, and reduce electrical interference. They can also be used in signal processing, such as for filtering purposes, to remove unwanted frequencies or to shape the output signal. They can also be used in radio frequency circuitry, where they can control the frequency of an oscillator and act as a buffer between different stages of the circuit.

Working Principle

The working principle of the fixed inductor is based on Faraday’s law of induction. This law states that whenever a conductor is placed in a changing magnetic field, it will induce an electric current in the conductor. By winding a coil of conductive wire around the inductor’s core, it will create a magnetic field when an alternating current is passed through it. This changing magnetic field will then induce an electric current in the coil of wire surrounding the core.

The magnitude of the induced current depends upon the number of turns in the coil, which is known as the inductance, or “L” value. This value determines the amount of resistance to change in the current flow in the circuit. The higher the inductance, the higher the resistance to change and the higher the level of electrical power which is stored in the inductor.

The inductor also acts as a filter, allowing certain frequencies and rejecting others. By varying the number of turns in the wire coil, it is possible to increase or decrease the inductance of the inductor, and thus its filtering characteristics. This can be useful for applications such as radio frequency (RF) or signal processing, where it is desired to accept certain frequencies or reject others.

The fixed inductor is a versatile component which can be used in many different types of electronic circuits. It is relatively simple to use and can be a cost effective solution for regulation of current and voltage, or for signal filtering applications. The exact type of inductor required will depend heavily on the type of circuit it is to be used in, and the specific requirements of the application.
