Fixed Inductors: SRU8043-120Y Application Field and Working Principle

A fixed inductor, such as the SRU8043-120Y, is a type of permanent magnet that can generate a steady flow of electrical current. The current is generated by the winding of its coils around a core material, such as iron. It is commonly used in applications such as power supplies, audio amplifiers, and frequency control systems.

The SRU8043-120Y is a radial-lead, surface-mount inductor, which is used in a variety of consumer electronic and automotive circuit designs. It is made of a high-permeability ferrite core and encapsulated in a plastic housing. The inductor is ideal for compact footprint applications. It has a 0.14 Ohms AC resistance and can handle a maximum of 120 mA of DC current.

Exploring the SRU8043-120Y Working Principle and Features

The SRU8043-120Y fixed inductor works on the principle of self-induction. It alters the flow of current in an electrical circuit due to the action of the magnetizing field created when the current passes through its coil. Since an inductor stores energy in its core, this causes a characteristic opposition or impedance to the current, which produces a voltage drop across its terminals.

The SRU8043-120Y is ideal for applications that require space-efficient surface-mount designs. It has a low DC resistance, enabling higher currents to be carried with minimal power losses. Its plastic casing prevents any heating effects caused by varying currents, helping preserve its operation in high-temperature conditions. The inductor also has a lower core loss compared to air-cored designs.

Applications of the SRU8043-120Y Fixed Inductor

The SRU8043-120Y fixed inductor finds application in a range of electronic circuits and devices. It is commonly used in power supplies, especially those with battery back-up circuits. The inductor can help to smooth out the voltage curve during startup and when power sources fail. It is also useful for audio amplifiers, as it can filter out unwanted frequencies and provide a cleaner signal.

Inductors are also commonly used in frequency control systems, such as oscillators and filters. The SRU8043-120Y inductor is suitable for use in both as its low resistance makes it ideal for fast frequency applications. In addition, the device\'s high current-handling capability makes it suitable for speed control circuits, such as in motors and drives.

Conclusion

The SRU8043-120Y fixed inductor is an ideal device for a range of consumer electronics and automotive applications. The high permeability of its core, low DC resistance and plastic casing make it suitable for use in compact, surface-mount designs. The inductor is capable of providing steady currents and is useful for smoothing out voltage curves, filtering out unwanted frequencies and speed control.
