Fixed inductors play an important role in many electronic circuits, providing essential components for power supplies, signal coupling and filtering. SCIHP0750-R47 is a popular fixed inductor widely used in a variety of applications thanks to its low cost, reliable performance and high power ratings. In this article, we will discuss the application fields and working principles of the SCIHP0750-R47.

Application Fields

The SCIHP0750-R47 is typically used in high-power switching applications such as on-off power supplies or DC-DC transformers. It can also be used for other high-frequency applications, such as in cell phone chargers, LED drivers, and automotive electrical systems. The SCIHP0750-R47 is also ideal for high-frequency power line communication (PLC) circuits, where it helps filter out unwanted electromagnetic interference (EMI).

Working Principle

The SCIHP0750-R47 consists of two windings of wire wound around an inductive core. When current is applied to the outermost winding, a magnetic field is generated around the core that creates a voltage in the other winding. This voltage is known as inductive coupling, or back EMF. It is the same principle that is at work in any transformer. As the current in the outer winding rises, the inductive action of the core creates a back EMF in the other winding that impedes the current flow. This is known as inductive reactance, and it is the basis for the inductor’s operation.

The amount of inductive reactance is determined by the size of the core material, the number of turns in each winding, and the frequency of the applied current. The larger the core material and the more turns in the winding, the higher the inductive reactance will be. Similarly, the higher the frequency of the applied current, the higher the inductive reactance will be.

The SCIHP0750-R47 is also designed to provide a high-power rating, with its current rating up to 50-60A. This high current rating means that it can be used in power supplies and other applications with higher power requirements. The SCIHP0750-R47 also has a relatively low insertion-loss, making it suitable for power line communication (PLC) circuits as well as other modern electronic applications.

Conclusion

The SCIHP0750-R47 is a versatile fixed inductor that is suitable for many high-power, high-frequency applications. It is designed to provide a high power rating, reliable performance and low insertion-loss. It is typically used in switching power supplies, DC-DC transformers, cell phone chargers, LED drivers, automotive electrical systems, and power line communication (PLC) circuits. The working principle of the SCIHP0750-R47 is based on the creation of a back EMF in the winding, which is caused by the inductive action of the core.
