Fixed Inductors refer to almost all types of inductor applications in electronic circuits. Depending on the requirement and application area, there is a wide selection of models that can be used for different applications. RL622-821K-RC is one of them. This article will cover the application field and working principle of this model.

Application Field

RL622-821K-RC is a high power wide range fixed inductor. It can be used in many different applications from DC-DC converters, DC-AC inverters, audio, automotive to industrial control. The inductor is especially useful for high current applications in motor drives. It has wire wound construction, ferrite core materials, and is rated at 68μH and 5A. In addition, it has a maximum self-resonant frequency of 95MHz, meaning it can be used in switching power supply applications with frequencies up to 95MHz.

Working Principle

All fixed inductors work on magnetic induction principle. This basic principle is the cornerstone of a coil or inductor which functions as an electrical device. The RL622-821K-RC inductor consists of a wire which is wound around the core material, in this case a ferrite core. When a current is passed through the inductor, a magnetic field is created. This magnetic field then induces a changing voltage, which in turn creates an alternating current. This is the basis of how inductors produce consistent voltage and current when under load.

The RL622-821K-RC inductor rated at 68μH and 5A is designed to work in high current applications. A larger inductor can handle larger currents. However, when the current is too high, the inductor can be damaged due to excessive heat. This is why the RL622-821K-RC is designed with a higher core material and wire winding to handle the larger currents of up to 5A.

Conclusion

The RL622-821K-RC is a high power wide range fixed inductor suitable for many applications. Its rated at 68μH and 5A and can be used in DC-DC converters, DC-AC inverters, audio, automotive to industrial control. Its wire wound construction and ferrite core materials make it capable of handling higher current up to 5A. This inductor works on magnetic induction principle which enables it to produce a consistent voltage and current when under load.
