MS75085-19RU

Fixed inductors are broadly used in various applications due to their low cost, tolerance, and price as an electronic component. Specifically, the MS75085-19RU, a type of 4-pin leaded fixed inductor, is not only commonly used in power supplies and antennas, but also for in-circuit applications. This article will discuss the application field and working principle of this type of fixed inductor.

Applications

The MS75085-19RU fixed inductors are versatile in their application fields, which can be subdivided into two categories: in-circuit applications and power-supply systems.

In-Circuit Applications

The MS75085-19RU fixed inductors can be used to design and construct various circuits, such as radio frequency (RF) circuits, audio amplifier circuits, and pulse circuits. Firstly, it can serve as an important component of RF circuits. Its characteristics of high inductance, low current and low frequency response make it suitable for capturing signals over a wide frequency range. Secondly, it is commonly used in audio frequency amplifiers. It has the ability to filter out unwanted frequencies and prevent noise from entering or exiting the circuit. Lastly, the fixed inductor can be utilized in pulse circuits. Its low inductance and high peak current capability make it a reliable component for handling sudden surges in a circuit.

Power-Supply Systems

In addition, fixed inductors can also be used in power-supply systems. In a power-supply system, the main function of the fixed inductor is to store energy in the form of magnetic field, which is then later released as electrical energy. This stored energy is used to power the different components within the system. For instance, in television sets, the combination of fixed inductors and capacitors is used to generate the high voltage needed to control the cathode ray tube. Additionally, MS75085-19RU fixed inductors are also used in switching power supplies, where they perform the function of storing energy when the current is “ON” and releasing it when the current is “OFF”, thus ensuring stable output and increased efficiency.

Working Principle

Fixed inductors work on the principle of electromagnetic induction. Electromagnetic induction is the phenomenon of generating electric current in a wire when it is placed in a changing magnetic field. When the current through the inductor is kept steady, a magnetic field develops around the wire due to the current. This movement of electric current creates a magnetic field which in turn creates an electric field and thus inducing an electric current. This process of electromagnetic induction results in the generation of electricity within the circuit, which is harnessed to power electronic components in the circuit.

The magnetic field created by the electric current in the inductor can be manipulated through the use of core materials. Metals like iron, ferrite, and silicon steel vary the amount of magnetic flux they can store and produce. As such, they are commonly used as core materials to increase the inductance of the inductor.

The working of the MS75085-19RU fixed inductor is based on the principles of electromagnetism. The inductor can be used to store electrical energy in the form of a magnetic field. This field, when released in the form of current, can then be used to power various electronic components in a circuit.

Conclusion

In conclusion, the MS75085-19RU fixed inductor is a reliable electronic component for many in-circuit applications and power-supply systems. It works on the basic principle of electromagnetic induction, where an electric current creates a magnetic field which in turn induces an electric current. It can also be used in various circuits, such as RF circuits, audio frequency amplifiers, and pulse circuits. As such, the MS75085-19RU fixed inductor is a versatile electronic component for multiple applications.
