Working Principle

Inductors are components in circuit boards that create an induced magnetic field when a current flows through them. The amount of the induced magnetic field is determined by the amount of current and the number of turns in the induction coil. The induced magnetic field can prefer or oppose the current flow. This behavior of the inductor is described as inductance. The current induces the magnetic field also causes a back electromotive force (EMF) which then opposes any change in the current flow. This opposing EMF is the inductive reactance.

Inductors have the property of storing energy in the magnetic field. This stored energy is released when the current is changed. This phenomenon is referred to as the inductor\'s self-induction. The MS75083-12ST has a 12mH inductance, which makes it suitable for use in instrumentation and data acquisition, telecommunications, automotive, and other applications.

The most common application of an inductor is in power supplies. An AC supply is rectified and filtered, before it is fed to the load. A large value electrolytic capacitor is used in series with the inductor to store energy. Whenever the voltage on the capacitor falls below the rectified AC voltage, the capacitor charges up again. This is because the current flowing through the inductor suppresses the fall in the capacitor voltage.

In addition, inductors can also be used to reduce the current in a circuit. A choke, for example, is a coil inductor used to reduce the current flowing in an AC circuit. The inductor creates an opposition to the current flow, which means only a limited amount of current can pass through it. Reactive components like these are essential to electrical and electronic circuits for various reasons, such as power conservation, current limiting, and signal filtering.

The MS75083-12ST is an example of a fixed inductor which is widely used in a variety of electronic and electrical systems. It has a maximum DC current of 1.5 A and an operating temperature range from -55°C to 125°C. This versatile inductor can be used in a variety of applications, including PWM controllers, inverters, motor drives, and other related applications.
