Fixed Inductors are electronic components with multiple layers of wire coiled around a ferromagnetic core. They are used to store energy in the form of a magnetic field and to produce inductive reactance in electronic circuits. The type of fixed inductor considered in this article is the SPM4020T-1R0M-CA02. This article will discuss the application field and working principle of this component.

The SPM4020T-1R0M-CA02 is typically used in an application that requires a high DC current with minimal losses. It can be used in commercial, medical, and automotive applications. In commercial applications, the SPM4020T-1R0M-CA02 can be used for AC line filters or switch mode power supplies. In medical applications, this type of inductor can be used in pacemakers or medical devices. It is also used in the automotive industry for ignition coils and fuel injectors.

The working principle of a fixed inductor is based on the fact that when current is applied to a coil of wire, a magnetic field is generated. This magnetic field is used to store energy and to produce inductive reactance in the circuit. The more coils that are used, the higher the inductance. This is because the magnetic flux is increased and the inductance is proportional to the number of coils. The SPM4020T-1R0M-CA02 has an inductance of 400mh and can handle a maximum DC current of 2A.

Apart from storing energy, fixed inductors can also be used to filter out high-frequency noise. This is done by using a coil with a higher inductance value, which causes the noise to bypass the inductor and not get transmitted to the rest of the circuit. By doing this, the signal is filtered and can remain clean.

Fixed inductors are also used in switched-mode power supplies to reduce the amount of switching losses. In a switched-mode power supply, an inductor is used to store energy and to provide a stable current flow. This ensures that the power output remains constant and that switching losses are minimized.

The SPM4020T-1R0M-CA02 is a very versatile fixed inductor and is suitable for many different applications. It can be used in high current applications, AC line filters, ignition coils, fuel injectors, and many other applications. It is also suitable for use in switched-mode power supplies, as it can provide a stable current flow and reduce switching losses.
