Fixed Inductors

Inductors, also known as coils, are widely used in electronic circuits to store energy in the form of a magnetic field. The RL110S-390L is a fixed inductor designed to meet the needs of modern electronic circuit design. This article will discuss the application fields and working principles of the RL110S-390L.

Application Fields

The RL110S-390L is designed for applications requiring a high level of inductance with low DC resistance. These applications typically are used in switch-mode power supplies where high currents are switched, switched-mode regulators and other electronic circuits which call for a high amount of inductance.The RL110S-390L has the advantage of being able to handle a wide range of frequencies without any significant changes in performance. This makes it useful for high-frequency applications such as SMPS (Switch Mode Power Supply) and UPS (Uninterruptible Power Supply).

Working Principle

The working principle of the RL110S-390L is based on that of an inductor. An inductor is a passive two-terminal electrical component that stores energy in a magnetic field when it is subjected to an electric current. When the current applied to an inductor is increased, the amount of energy stored in the magnetic field also increases, thus increasing the inductance. This increase in inductance causes the current to increase, which in turn increases the amount of energy stored in the magnetic field. This process is known as inductance-current feedback or L-I loop.The RL110S-390L is designed to take advantage of this phenomenon and provides a much higher level of inductance than most other inductors. This makes it particularly useful for applications that require high levels of current to be switched.

Conclusion

The RL110S-390L is a versatile fixed inductor designed for applications requiring a high level of inductance with low DC resistance. It is well suited for high-frequency applications such as SMPS and UPS, as it can maintain high performance over a wide range of frequencies. Its working principle is based on the principle of inductance-current feedback or L-I loop.
