Fixed inductors such as the SC5022F-681 are classified as a type of passive component used in electrical circuits to store energy. Being categorized as a type of inductor, a fixed inductor is designed to oppose any change in current passing through it. It is capable of generating magnetic fields in response to the flow of electric current. The main application where fixed inductors are used is for power conversion, such as step-up and step-down converters, as well as to filter out signal frequencies.

In terms of its construction, fixed inductors are made up of a core and several windings of copper or enameled wire, all encased within a suitable insulating material. The core material will greatly depend on the category of inductor, however ferromagnetic cores are the most common type, as these create a strong magnetic field which aids in inductor’s operations. The type and number of windings will vary, as these factors will determine the inductance value of the component. In addition, a fixed inductor will be rated based on it’s maximum allowable voltage and rated current.

The SC5022F-681 fixed inductor is designed by the manufacturer Sumida Electronics as an SMD type component, featuring a ceramic encased core and windings of enameled wire. It is rated for an operational voltage of 16V and passing current of 680mA. Furthermore, the electrical characteristics of the component are a rated inductance of 3.3 mH and an impedance of 1700m ohm at a frequency of 0.1 MHz. This makes the SC5022F-681 a suitable component for use in common mode noise suppression, over-current protection circuits, as well as a wide range of common filter circuits.

When it comes to the working principle of a fixed inductor, the phenomenon of magnetic induction plays an important role. As was stated earlier, the fixed inductor consists of a core, which is typically made of ferromagnetic material, and a winding of copper or enameled wire. When an electric current flows through the wire, it will generate a magnetic field inside the ferromagnetic core material. In turn, this magnetic field will induce a back EMF voltage in the wire itself, thus this voltage opposes the current flow, in accordance with Faraday’s law of induction, creating an inductive reactance.

The inductive reactance can be calculated using an equation and is given by X_L=2πf L. Here X_L represents the inductive reactance in ohms, with f representing the frequency of input current, and L representing the inductance in henrys. When the frequency of input current is high, the inductive reactance will become very large, thus limiting the amount of current flow to the inductor. This phenomenon is leveraged to achieve various goals, such as power conversion, filtering, and signal conditioning.

In conclusion, fixed inductors such as the SC5022F-681 are a type of component used for various applications in electrical engineering. It leverages the phenomenon of magnetic induction to oppose a change in current and generate an inductive reactance, this being the scientific principle behind its working. In addition, with an operational voltage of 16V and a passing current of 680mA, the SC5022F-681 can be used for common mode noise suppression, over-current protection circuits, and many types of filter circuits. In this way, fixed inductors can be seen to be a very versatile and invaluable component in the electronics engineering industry.
