Introduction

Fixed inductors are components that absorb or store energy in an inductor, primarily composed of an insulated core and winding that creates a magnetic field when an electrical current passage through it. One popular fixed inductor is the SDR0302-1R2ML, used in various applications for 40 kHz to 4 GHz frequency range and is used in a variety of fields such as energy storage, telecommunications, and high frequency communication. This article will discuss the SDR0302-1R2ML, its application field and working principle, in order to provide a better understanding on the inductor\'s functions and capabilities.

Application Field

The SDR0302-1R2ML, this single-layer air-core inductor is a popular choice in a wide range of applications due to its low power consumption, high Q factor, and excellent power handling capacity. With a frequency range of 40 kHz to 4 GHz, SDR0302-1R2ML is suitable for use in various fields such as energy storage, telecommunications, and high frequency communication.In energy storage, SDR0302-1R2ML can simulate an inductor with low cost, high efficiency, and strong stability, which can significantly reduce the size and cost of energy storage system. Furthermore, this type of inductor can be used in a wide range of power conversion applications, such as resonance coupling circuits, high frequency boost circuits, and low noise power conversion.The SDR0302-1R2ML is also especially used in telecommunications and high frequency communication due to its physical characteristics; its core is designed to reduce high frequency loss. Moreover, because of its superior performance in terms of energy storage, charging and discharging, and high frequency transmission, it is suitable for high-tech fields like radar, navigation and communication, micro wave devices, and satellite systems.< h2>Working PrincipleThe working principle of the SDR0302-1R2ML is based on Faraday\'s Law of Induction, which states that when a magnet is moved through a conductor, an electric current is induced in the conductor. When a current is passed through the SDR0302-1R2ML, it creates a magnetic field that stores a certain amount of energy. The energy stored is then released into the system when the current is removed.In the SDR0302-1R2ML, the electric current that is generated passes through the inductor’s winding. The magnetic field that is develops induces a current that can be used to store energy. As the current passes through the inductor’s core, the energy stored increases until the current passes through the inductor and the process starts again.The SDR0302-1R2ML works on the principle of inductance, which is a property of an electrical conductor to resist a change in the electric current passing through it. As the current passes through the inductor, a magnetic field is generated and this induces a voltage, which opposes the change in the current. This produces a “back EMF”, or an EMF that opposes the current, which is a general principle of induction. The amount of voltage generated is proportional to the amount of current, but inversely proportional to the frequency of the current.

Conclusion

The SDR0302-1R2ML is a fixed inductor used in a variety of applications such as energy storage, telecommunications and high frequency communication. This type of inductor has a wide frequency range and works on the principle of Faraday’s Law of Induction, where it creates and stores an electric current and an induced voltage when a current is passed through it. The SDR0302-1R2ML is highly efficient, economical and suitable for a wide range of applications, making it a popular choice for various industries.
