Fixed inductors are widely used in mostly filtering and snubbing applications for power electronic designs. They are used to provide a special type of energy storage in an electromagnetic field that can be used to filter high frequencies and provide reliable snubbing. The common characteristics of fixed inductors are lamination, low resistance, high current handling capability, high frequency rate, and low voltage drop. The RL855-561K-RC Inductor is a popular fixed inductor specifically designed to serve power electronic designs. This article will discuss the application field and working principle of the RL855-561K-RC.

Application Field of the RL855-561K-RC

The RL855-561K-RC is a fixed inductor designed to serve power electronic designs by offering performance faithful to the feedback of the circuit designer. It is a suitable silicon oil filled inductor for use in applications in rectifiers, pulsed loads and power supply feedback. Typical applications of the RL855-561K-RC include snubber circuits for SCRs and IGBTs, clamp snubbers, and power supply circuits that require tight regulation of the current feedback. It can also be used in SMPS, inverters, switching mode power supplies, step up/down converters and in high frequency power electronics.

Due to its outstanding features, good thermal performance and high power density, the RL855-561K-RC is capable of handling up to 1.8 kW of power in a 5µH version. This high power handling capability allows it to be used in a wider range of applications, ranging from to low ampere to high ampere current applications.

Working Principle of the RL855-561K-RC

The RL855-561K-RC Inductor operates on the principle of electromagnetic induction, in which a current passes through a conductor and an EMF is generated according to Faraday’s law of induction. This EMF is the result of a change in the magnetic field intensity passing through the coil.

When the current passing through the coil changes, this induces a voltage in the coil that opposes the change of current. This generates what is known as “Back-emf or Counter EMF” which is counter to the applied voltage. This helps to stabilize the current in the circuit and reduce current surges. Also, this action helps to keep the current load constant and low.

Furthermore, the RL855-561K-RC inductor is designed to have a narrow frequency response, providing efficient filtering of high frequency noise and HF signals. Its low copper losses at high frequencies means that it is well suited for use in circuits with high frequency content and tight regulation.

Conclusion

The RL855-561K-RC Inductor is a great fixed inductor designed and tailored specifically for power electronic designs. Its narrow frequency response allows it to filter high frequency signals with excellent efficiency. Moreover, its high power handling capability and excellent thermal performance make it ideal for use in a wide variety of applications.
