Introduction
Fixed inductors are devices consisting of coils of insulated wire wound on a core or an air gap. These are used in many applications in electrical and electronic circuits. The MLG0402Q3N5CT000 is a fixed inductor manufactured by Murata Electronics North America, Inc. which is designed for high-speed applications. In this article, we will discuss the application field and working principle of MLG0402Q3N5CT000.

Application Field
The MLG0402Q3N5CT000 fixed inductor is suitable for use in a wide array of applications such as high-frequency switching converters, switch-mode power supplies, RF circuits, antennas, and EMI filters. It is used in many high-speed designs due to its high efficiency, high current-handling capability, and low insertion losses.In particular, this inductor is used in a power-supply applications where a power-supply switch is used to ramp up the voltage from one rail to another. It is also used in high-frequency circuits such as variable-frequency drives, inverters, and other machines that require high-frequency signals. Additionally, it is used in antenna and EMI filtering circuits to limit the voltage and current in order to reduce spurious signal propagation.

Working Principle
The working principle of the MLG0402Q3N5CT000 fixed inductor is based on Faraday\'s law of induction which states that a potential difference is induced in a looped electrical conductor when the magnetic flux through the loop changes. When a voltage is applied to the loop, the magnetic flux builds up and stores energy in the form of a magnetic field. When the voltage is removed, the magnetic field is released, inducing a voltage in the conductor.The MLG0402Q3N5CT000 fixed inductor consists of a wound coil of insulated copper wire which forms an inductor. When a varying voltage is applied to the inductor, a changing magnetic field is created, inducing an electrical current in the winding. The inductor stores some of the energy from the current, effectively ‘smoothing’ the voltage waveform. This reduces the rate at which the voltage increases or decreases in the circuit, resulting in a smoother output voltage waveform.

Conclusion
The MLG0402Q3N5CT000 fixed inductor is a versatile device designed for high-speed applications. It is suitable for use in power-supply applications, high-frequency circuits, antennas, and EMI filters. Its working principle is based on Faraday\'s law of induction whereby a changing magnetic field induced by a varying voltage induces a current in a looped conductor. This current is then stored in the inductor and used to ‘smooth’ the voltage waveform of the circuit, ensuring a clean output signal.
