Fixed inductors are components with relatively simple operation, used in a wide variety of electronic applications. The LBC3225T100KRV is a popular fixed inductor, employed in many commercial, industrial and aerospace applications. In this article, we’ll explore the LBC3225T100KRV inductor’s application field and working principle.

Application Field and Feature of the LBC3225T100KRV

The LBC3225T100KRV is a surface mount power inductor, designed primarily for use in power amplifiers and other high current applications demanding exceptional low resistance. It offers excellent thermal properties, with an operating temperature range of -55 to +105°C.

The LBC3225T100KRV provides a very stable inductance, excellent EMI repression and an improved impedance compared to many common step-up transformers and ferrite inductors used in power amplifiers. Its structure features a low interwinding capacitance and a high immunity to coupled and radiated interference. It also has a very low DC resistance and unloaded losses. These benefits all combine to make the LBC3225T100KRV an ideal choice for applications in which power amplifiers and other high current applications require a high level of electrical noise protection.

Working Principle

The working principle of the LBC3225T100KRV lies in its ability to form a self-contained electromagnetic field. In short, when electricity flows through the inductor\'s coils, it creates a magnetic field which interacts with the surrounding electric field. This interaction then leads to an electromotive force being also generated.

This process can be seen in general terms in the following illustration:

In this diagram, the inductor can be seen consisting of two coils, a core, and a core-shield to prevent electromagnetic interference (EMI). The core enables more efficient energy transfer between the inductor coils, and the core shield helps reduce external interference.

In addition, the two coils wrapped around the core of the inductor create a feedback loop which enables the inductor to create a self-contained electromagnetic field. This field is what ultimately enables the inductor to reduce electrical noise, while maintaining a high level of efficiency.

Conclusion

In conclusion, the LBC3225T100KRV is a common and useful fixed inductor used in many high-power amplifier applications. It offers excellent thermal properties, low resistance, and a high degree of electrical noise protection. Its working principle is based on the creation of a self-contained electromagnetic field through two coils wrapped around a core, and a core-shield to reduce external interference.
