Fixed inductors or discrete inductors are used to create inductance in a circuit, typically in radio frequencies and other electronic applications. The SRP4020FA-2R2M is a type of fixed inductor, manufactured by Samsons Research, Inc. As of 2020, this device is widely used in automotive, medical and consumer products.

The SRP4020FA-2R2M has a rated inductance of 2.2 mH and operates at a maximum current of 5.5A. This inductor is constructed from ferrite beads with a printed board embedded between them. The actual inductance value may be different than that specified. SRP4020FA-2R2M is also RoHS compliant, according to the SRP4020FA-2R2M datasheet provided by Samsons Research.

The SRP4020FA-2R2M fixed inductor is a component used in the field of analog and digital electronic circuits. As it has a very low self-inductance rating, it is primarily used as an energy storage device due to the induced electromotive force it produces. As a result, it can be used in various applications, including filters, signal snubbers, voltage regulators, power supplies, surge protectors, motor speed control and oscillators. It is also often used to reduce the amount of interference generated by a given circuit.

Fixed inductors, like the SRP4020FA-2R2M, operate on the principle of inductance — the ability of an electrical conductor to store energy in the form of electromagnetic fields. This is done by inducing a magnetic field in a coil of wire when electric current is passed through it. To this end, fixed inductors are usually composed of electrical conductors coiled together to create a tightly-oriented magnetic core.

The electrical properties of an inductor depend on the alternating nature of the current that is passed through it. As its current alternates at a given frequency, an inductor’s current waveform is modified by its ability to store energy in the form of a magnetic field. This phenomenon is referred to as reactance — the inductive response of the device to alternating electrical currents.

The basic idea behind using an inductor is to store energy in a given circuit, or to limit the amount of energy that is allowed to pass through it. In short, by taking advantage of the principle of inductance, designers can create a device that can selectively filter currents and voltages in an electronic circuit, thus allowing only the desired elements to pass through.

Inductors are also desirable due to their high power density. As they rely on the principle of inductance, such components can be housed in a relatively small form factor, yet they still provide a sufficient amount of power. This makes them ideal for applications in space constrained environments, such as within cell phones and other mobile devices.

Ultimately, the SRP4020FA-2R2M is a type of fixed inductor that is designed to facilitate the flow of alternating current through an electrical circuit. It relies on the principle of inductance to induce an electromotive force and thereby store energy within the device as a magnetic field. Moreover, the SRP4020FA-2R2M can be used for a variety of purposes, including filters, signal snubbers, and voltage regulators. This makes it an ideal choice for those who need a high-power density component that is resistant to interference.
