Introduction

Fixed inductors are widely used in many applications such as filtering, matching, resonance, and impedance conversion in electronic circuits. They can be found in most electronic circuits because they are able to efficiently convert AC current into magnetic fields. The 21000LL-4R7-V-RC is a specific type of fixed inductor and this article will detail the application field and working principle of the 21000LL-4R7-V-RC fixed inductor.

Application Field of 21000LL-4R7-V-RC Fixed Inductor

The 21000LL-4R7-V-RC fixed inductor is generally used as an RF component for radio transceiver applications, due to its good electrical characteristics. The power consumption is relatively low, allowing for a long lifetime of the component. It is also used in RF power line filters, RF voltage dividers, and RF power amplifiers.

Working Principle of 21000LL-4R7-V-RC Fixed Inductor

The 21000LL-4R7-V-RC fixed inductor works by allowing a varying electric current to pass through it, producing a magnetic field. This magnetic field is used to induce a voltage in the inductor, which is then used to power the attached circuit. The current is limited by the amount of magnetic field produced, which depends on the number of turns in the inductor and the amount of current flowing through it.The material used to construct the core of the inductor plays a large role in determining the inductance of the component. Commonly used materials include ferrite, iron powder, and air. The design of the inductor also plays a role in the amount of current it can handle and the amount of voltage which can be induced.

Conclusion

The 21000LL-4R7-V-RC fixed inductor is a type of inductor used in RF applications. This type of inductor works by allowing a varying current to pass through it, which induces a voltage based on the magnetic field produced. The core material used and the shape of the inductor both influence the inductance as well as the current limit of the inductor. This type of fixed inductor can be used in RF power line filters, RF voltage dividers, and RF power amplifiers.
