Fixed Inductors

Fixed inductors are electrical components that are used to store energy in the form of electrical current. They have a wide range of applications and are commonly used in various types of electronics to achieve specific tasks. The 4501R- 120M is one such inductor, and is most commonly used for high frequency filtering and blocking applications. In this article, we will explore the application field and working principle of the 4501R-120M.

Application Field

The 4501R-120M is a high-frequency filtering inductor that can be used in various types of applications. It is most commonly used in LCD Monitors, Mobile Phones, Cellular Handsets, Base Stations, Set Top Boxes, Automotive Electronics, Medical Electronics, Home Appliances, and other general-purpose electronic devices. In these devices, it is used for the purpose of suppressing or blocking unwanted high-frequency signals while allowing desired signals to pass through.

Working Principle

Inductors can be thought of as a coil of wire with a core, usually ferromagnetic, as the center. The winding of the coil is connected to the supply voltage, and a current is induced in the coil. This induces a magnetic field. This magnetic field, in turn, interacts with the core of the inductor to produce the desired effect. In the case of the 4501R-120M, that effect is filtering and blocking. The inductor acts as a barrier, blocking out the unwanted high-frequency signals. The inductor also acts as a filter, allowing the desired low-frequency signals to pass through.

The inductance of this inductor is determined by the number of turns of coil and the amount of core material used. The larger the core, the more turns of coil required to achieve the same amount of inductance. The inductance is also dependent on the area of the core material. The larger the area, the more inductance the inductor can achieve.

The impedance of the inductor is also affected by its inductance. This means that the higher the inductance, the higher the impedance. The impedance of the 4501R-120M is matched to the impedances of the other components in the circuit to ensure proper performance. Additionally, it needs to have a low voltage rating in order to prevent unwanted current passing through.

Conclusion

The 4501R-120M is a high-frequency filtering inductor that can be used in a wide range of applications. It is used for the purpose of suppressing or blocking unwanted signals, while allowing desired signals to pass through. The inductance and impedance are determined by the number of turns in the coil and the core material, and the voltage rating must be kept low in order to prevent unwanted current passing through.
