Introduction

Fixed inductors are passive electrical components that can store electrical energy in the form of a magnetic field when electric current is passed through them. They are composed of a coil of wire, and there are many types of fixed inductors available on the market. One of these is the RL895-221K-RC, a ceramic core inductor that’s suitable for a range of applications. In this article, we\'ll take a look at the application field and working principle of the RL895-221K-RC.

Application field

The RL895-221K-RC fixed inductor has a wide range of applications. It can be used for various types of power supplies, like switching mode power supplies (SMPS) or linear power supplies. It’s also useful for DC-DC converters, transformers, or storage systems. Additionally, the RL895-221K-RC is suitable for RF circuits, as it can be used as an RF choke.

Working principle

Fixed inductors work on the principle of electromagnetic induction. When electric current passes through a coil, a magnetic field is created, and this magnetic field is what stores the energy. In the case of the RL895-221K-RC, this energy is stored in the form of a magnetized ceramic core.When the current flow is reversed, the magnetic field collapses and the stored energy is then released as an opposing current. This creates an opposing magnetic field which then acts as an inductor. The inductance is determined by the length of the wire coil and the diameter of the core.The RL895-221K-RC fixed inductor has an inductance of 221KH. This implies that it can store a large amount of energy, making it suitable for a wide range of applications.

Conclusion

To summarize, the RL895-221K-RC is a fixed inductor that has a wide range of application fields. It’s most commonly used in power supplies, RF circuits, transformers, and storage systems. It can store a large amount of energy due to its inductance of 221KH. Its working principle is based on the concept of electromagnetic induction, wherein a magnetic field is generated when an electric current passes through a coil. This magnetic field is what stores the energy.
