Fixed inductors are electrical components which are used to store electrical energy or transfer current in a circuit. They are typically composed of a coil of wire wound around a core, and may be made of materials such as ferrite, carbon, or air core. These components are available in variety of shapes and sizes, and have a wide range of applications. One of the most commonly used fixed inductors is the RL622-220K-RC, and its applications and working principles are discussed here.

The RL622-220K-RC fixed inductor is designed for use in applications such as voltage regulators, noise suppression, radio frequency interference (RFI) filtering, power supply circuits, switching power supplies, and other power supply filtering applications. The inductor features a copper ribbon wire winding, which increases component efficiency and helps provide superior power output. It also features a molded ferrite core, which provides excellent frequency and temperature stability, making the inductor suitable for use in high frequency circuits.

The RL622-220K-RC fixed inductor has a rated inductance of 220 micro-henries (µH) and a DC resistance of 0.08 ohms. The rated current is 540 mA and the rated voltage is 0.5 VDC. The inductor also has a low frequency cut-off at 9 kHz, which helps in noise suppression. Due to the low DC resistance and the low frequency cut-off, the RL622-220K-RC is excellent for use in audio applications such as power amplifiers and speakers.

The working principle of fixed inductors is based on Faraday’s law of induction. This law states that when an AC or DC current is passed through an inductor, a voltage is induced in the opposite direction of the current flow. The induced voltage is proportional to the number of turns in the coil and the frequency of the current. Thus, by controlling the current, it is possible to regulate the voltage output.

As the current through an inductor increases, so does the magnetic field surrounding the inductor. This increasing flux induces a current in the opposite direction, thus reducing the current. The amount of current that is induced is dependent on the inductance of the inductor and the amount of current that is entering the circuit. This property of reducing current makes inductors suitable for applications such as voltage regulators and power supplies.

Fixed inductors are used in a wide range of applications, and the RL622-220K-RC is no exception. This component is used for voltage regulation, noise suppression, RFI filtering, power supply regulation, and more. Its low DC resistance and low frequency cut-off make it particularly suited for use in audio applications. This versatility makes the RL622-220K-RC fixed inductor a popular choice in many applications, and it is sure to remain a valuable component in the future.
