Introduction

Fixed inductors are electrical components that are designed to create a fixed inductance in a circuit. They are commonly used as part of filter circuits or oscillators, where they are called inductors. The RL855-471K-RC is a fixed inductor component of the type commonly known as a "square inductor." This component can be used in various applications, and its working principle is fairly straightforward.

Application Field

The RL855-471K-RC fixed inductor can be used in a wide variety of applications. It is commonly used in filter circuits, such as radio receivers and oscillators. This type of inductor can also be used in wireless communication systems, audio amplifiers, and power supply units.The RL855-471K-RC has a rated current of 1.2A and a rated voltage of 75V. This makes it well-suited for use as a current-limiting inductor in many circuits. In addition, it has a low resistance to minimize power losses. This makes it an ideal choice for high-current applications, such as motors and power supplies.

Working Principle

The working principle of a fixed inductor is quite simple. When a current is passed through the inductor, it induces a magnetic field which, in turn, induces an opposing voltage. This voltage opposes the applied current, creating an inductive reactance that limits the flow of current through the inductor.The RL855-471K-RC fixed inductor is designed to provide a specific inductance value. The inductance value is determined by the size, shape, and material of the inductor. Therefore, the RL855-471K-RC will provide the same inductance value regardless of the applied voltage or current.

Conclusion

In conclusion, the RL855-471K-RC fixed inductor is a reliable component designed for a variety of applications. It has a rated current of 1.2A and a rated voltage of 75V, which makes it well-suited for many current-limiting applications. Moreover, its simple working principle means that it provides a constant inductance value despite fluctuations in voltage or current. For this reason, it is a popular component for use in filter circuits, wireless communication systems, audio amplifiers, and power supply units.
