Fixed Inductors

Fixed inductors, also known as chokes, are electrical components that store energy in the form of a magnetic field when an electrical current passes through them. The VLCF4028T-4R7N1R5-2 is a type of fixed inductor that is utilized in electrical engineering applications. The physical structure of the VLCF4028T-4R7N1R5-2 inductor is composed of a conductive coil winding that is encapsulated in a molded case, usually made out of plastic, ceramic, or metal. The core of the inductor is composed of magnetically permeable materials such as iron or powdered aluminum which helps to concentrate the magnetic field.The primary purpose of the VLCF4028T-4R7N1R5-2 inductor is to store energy, as electrical current passes through it, in the form of a magnetic field. When the current is removed, the stored energy is then gradually released back into the circuit. The rate at which the energy is released is determined by the inductance rating of the specific inductor and is typically measured in units of Henries (H). The VLCF4028T-4R7N1R5-2 inductor is well-suited for use in various applications because of its small size, low profile, and highly efficient electrical performance. It is typically used in DC-DC converters, switch mode power supplies, and other power management systems for regulating the flow of current in a circuit. The inductor is also widely used in other electrical engineering devices and systems such as electromechanical resonance circuits, radio frequency interference filters, and voltage regulation sensors. The working principle of the VLCF4028T-4R7N1R5-2 fixed inductor is based on Faraday\'s law of induction which states that when a conductor, such as a coil of wire, is placed in a changing magnetic field, a current will be induced in the conductor. This is because the changing magnetic field induces an electric field which in turn causes a current to flow within the coil. This is the same principle that is utilized in the VLCF4028T-4R7N1R5-2 inductor where the electrical current produces a magnetic field which stores energy until the current is removed. The electrical specifications of the VLCF4028T-4R7N1R5-2 inductor may vary depending on the manufacturer but typically include a DC current rating of 0.36 amps, a rated inductance of 4.7uH ±20%, and a typical Q factor of 70. The VLCF4028T-4R7N1R5-2 inductor also has a self-resonant frequency of 218MHz, a rated current of 1.78A, and a maximum operating temperature range of 105°C. In conclusion, the VLCF4028T-4R7N1R5-2 is a type of fixed inductor that is widely used in various electrical engineering applications. The physical structure of the inductor consists of a conductive coil which is encapsulated in a molded case. The primary purpose of the VLCF4028T-4R7N1R5-2 inductor is to store energy, as electrical current passes through it, in the form of a magnetic field, utilizing Faraday\'s law of induction. The electrical specifications of the VLCF4028T-4R7N1R5-2 inductor include a rated inductance of 4.7uH ±20%, a DC current rating of 0.36 amps, and a maximum operating temperature range of 105°C.
