Fixed Inductors

Fixed inductors, also known as inductor coils, are passive components used in electronics circuitry to create a magnetic field and store electrical energy. They contain a core made of wire that is wound around a ferromagnetic material. They are available in a wide range of shapes, sizes, and inductance.The 5728 is a fixed inductor or coil which has a rated inductance of 0.01 μH (microhenries), a tolerance of 0.01%, and an operating temperature range of -40°C to +85°C. It is constructed with a two-level windings of copper wire wound around a special core. The coil is then coated with a varnished outer-layer to provide electrical insulation from the core.

Application Field

Fixed inductors can be used in a variety of applications, such as signal conditioning, filter networks, transducers, analog-to-digital converters, switching power supplies, and RF amplifiers. They are also used to provide high frequency signals and act as a kind of “ energy storage ” for feedback circuits.The 5728 is specifically designed for use in radio frequency (RF) circuits. It is especially useful for high frequency and high impedance applications, and can be used to increase the efficiency of a radio frequency circuit. It can also be used to minimize noise in a radio frequency circuit.

Working Principle

The working principle of an inductor is based on the relationship between an electric current and a magnetic field. When a current flows through a wire, it creates a magnetic field. This magnetic field has a certain direction, which is determined by the length of the wire and the direction of the current. An inductor is a coil of wire and magnetic core material, which creates a larger magnetic field when a current passes through it.The 5728 has an inductive reactance of 0.02 ohms. When a current passes through the coil, it creates an electromagnetic field that is proportional to the amount of current and the number of turns in the coil. This electromagnetic field then interacts with the core material, further increasing the magnetic field strength.The magnetic field created by the inductor also has an effect on the electrical current. As the current passes through the inductor, it is resisted by the inductive reactance of the coil. This resistance causes an increase in the voltage across the inductor, allowing the circuit to store more energy and improving the efficiency of the circuit.The electromagnetic field surrounding the 5728 also helps to reduce electrical noise, which is particularly important in RF circuits. By limiting the amount of noise, it helps to ensure that the received signal is of a higher quality.
