Fixed Inductors

Fixed inductors are passive electronic components which on their own store and release energy. They are used mainly in filter circuits, voltage regulation, radio tuners and other types of electronic circuits. This article will discuss the application field and working principle of ASPIAIG-F5020-R47M-T.

Application Field

ASPIAIG-F5020-R47M-T inductors are mainly used in power supply systems, such as for antenna tuning and mobile phone basestation, to restrict the AC current\'s flow. They are also often used in RF circuits and audio circuits, to reduce interference, suppress noise and to balance signal levels. Furthermore, they are common in radio tuners, voltage regulators, logic circuits, oscillators, amplifiers, inverters and DC-DC converters, as they can also serve as efficient current converters. In general, they are often included in any circuit where current must be filtered and regulated in order to meet required parameters.

Working Principle

An inductor is a closed loop of conductor, usually formed into a coil by winding it around a core. When an electrical current is passed though this coil, it creates a magnetic field in the core. This magnetic field causes the current to be stored in the form of a magnetic field around the coil and is released back into the circuit when the current flow is reversed or interrupted. This phenomenon is known as inductance. The amount of stored energy depends on the strength of the magnetic field, which is determined by the number of turns of the coil and the core material. The ASPIAIG-F5020-R47M-T inductor is especially well-suited for applications in which high-Q inductance is required, meaning that the effective or real inductance value is much higher than the inductance value without the core.

The ASPIAIG-F5020-R47M-T is a resistor-equipped inductor, designed to provide a flat impedance curve over a wide frequency range. The resistor works as an RF choke, limiting the current that flows through the inductor, while the inductor provides high-Q inductance values. This combination is designed to provide high isolation, while maintaining optimal performance in the frequency range of interest.

In conclusion, the ASPIAIG-F5020-R47M-T is a fixed inductor which can be used in a variety of filter, voltage regulation, radio tuner, and other electronic circuits. Its combination of resistor and high-Q inductance makes it an ideal choice for applications requiring a wide range of high isolation.
