## IntroductionFixed inductors are passive components used to create a magnetic field or store energy in an electric circuit. They can be found in a wide range of applications from amplifiers to signal processors, frequency blockers to radio receivers. The VLF4014ST-4R7M1R4 is one of many inductors on the market. This article will discuss the application field and working principle of the VLF4014ST-4R7M1R4 in order to better understand its capabilities and function.## Application FieldThe VLF4014ST-4R7M1R4 offers improved performance in mobile phones, tablets, and other wireless communication products. It features a low-resistance copper inner core that enables extremely low-power consumption, allowing it to extend battery life. The device also has a small size and low height profile, which are important traits for components incorporated into portable electronics. Furthermore, the inductor has an approved temperature range of -40°C to +90°C, making it suitable for operation in a variety of rugged and extreme environments.The VLF4014ST-4R7M1R4 is also used in audio equipment applications such as amplifiers, loudspeakers, and microphones. Its compact size allows it to be easily embedded into the devices’ circuit boards, reducing the amount of space needed for the component. The device is also capable of suppressing EMI radiation, which is an important requirement for signals in audio equipment.## Working PrincipleThe working principle of a fixed inductor is based on Faraday’s Law of Induction. According to this law, a magnetic field is produced when an electric current passes through a circuit. This in turn generates a voltage, which is known as the induced voltage.The VLF4014ST-4R7M1R4 works by controlling the strength of the magnetic field produced by the electric current in order to store energy in an electric circuit. This is done by varying the value of the inductor, allowing the user to select the best value for the application.The device also features a low-resistance copper inner core, which allows it to generate a much stronger magnetic field with less energy. This in turn helps to reduce power consumption and increase efficiency.## ConclusionThe VLF4014ST-4R7M1R4 is a versatile fixed inductor that can be used in a wide range of applications from mobile phone circuits to audio equipment. It features a low-resistance copper inner core, allowing it to generate a stronger magnetic field with less energy, and has a small size and low height profile, making it suitable for incorporation into portable electronics. Its ability to suppress EMI radiation is an important asset for audio equipment applications. The Working principle of a fixed inductor is based on Faraday’s law of induction, which explains the generation of a voltage by a current passing through a magnetic field.
