Working Principle

The RL622-682K-RC utilizes the basic principles of an inductor in order to fulfill its designated purpose. Basic inductors are formed from conducting wire wound around a core material and the inductance is also dependent on the shape of the inductor coils. The RL622-682K-RC fixed inductor works by limiting the amount of current that flows through it, and this is done by the magnetic field created by an electrical signal passing through the coil winding. This magnetic field opposes any change in current, and as a result, the current is limited.

The inductance of the RL622-682K-RC is typically between 68uH and 2.2mH depending on the type chosen. The self-resonant frequency (SRF) of this inductor is typically between 15kHz and 400kHz, which can be tuned with an external capacitor if necessary. Additionally, the winding resistance of the RL622-682K-RC is usually between 0.40 ohms and 1.6 ohms.

Conclusion

The RL622-682K-RC fixed inductor is a useful component for a wide variety of applications, including voltage stabilization, current control, differential-mode interference suppression and filter inductors. It works using the basic principles of an inductor, whereby a magnetic field is created in opposition to the current flow to limit it. The inductance, SRF and winding resistance of the RL622-682K-RC component can be tuned with an external capacitor if necessary. Overall, this fixed inductor offers a reliable and cost effective solution for many applications.
