Fixed inductors are components that store electrical energy in the form of a magnetic field. They are used in a variety of applications, from Automotive Electronics to Power Supplies and from Consumer Electronics to Industrial Automation. The LGJ7045TC-2R2N-D is an example of a fixed inductor, and its application field and working principle will be discussed below.

Principle of Operation

A fixed inductor is composed of two main components: the core and the winding. The core contains a magnetic material such as iron, which is arranged in a way that when a current is passed through the winding, it is magnetically coupled to the core and creates a magnetic field. The magnitude of the magnetic field depends on the amount of current passing through the winding and the permeability of the core.
The changing magnetic field then induces a voltage in the winding in accordance with Faraday’s law of induction. The magnitude of the induced voltage is proportional to the rate of change of the magnetic field, and thus the rate of change of the current. For this reason, the inductance value is directly proportional to the size of the core and the amount of turns in the winding.

Application Field

The LGJ7045TC-2R2N-D fixed inductor can be used in a variety of applications in both analog and digital circuits. Its wide operating temperature range allows it to be used in both high temperature industrial applications as low temperature consumer products.
In analog circuits, it is often used to filter or shape waveforms, for noise reduction or for RFI/EMI filtration. In digital circuits, it is often used as an output filter to reduce high frequency switching noise caused by digital circuits. In power supplies, it can be used to store energy when voltage and current levels vary. It can also be used in voltage regulation and in resonant circuits for frequency control.

Conclusion

The LGJ7045TC-2R2N-D fixed inductor is a versatile component that can be used in a wide variety of applications, from consumer electronics to industrial automation. Its principle of operation is based on Faraday’s law of induction, and its performance can be adjusted by changing the size of the core and the number of turns in the winding. With its wide operating temperature range and robust design, it is a suitable choice for a variety of applications.
