Fixed Inductors - 4470-48G application field and working principle

A fixed inductor (also known as an inductor, choke, or coil) is a type of passive electrical component, typically used as part of an electrical circuit in order to modify or control the flow of current. The most common fixed inductor consists of a coil of copper or other metal wire wrapped around a core of ferrite or other magnetic material.

Application Fields of 4470-48G

The 4470-48G is a fixed inductor from the Bourns product line. It is suitable for use in a variety of applications, from medical devices and automotive electronics to consumer electronics and telecommunications equipment. It is particularly well-suited for high-frequency applications, due to its small size and its ability to suppress noise in digital circuits.

The 4470-48G is also a very reliable fixed inductor, with an operating temperature range of -40°C to +85°C and a maximum rated voltage of 16VDC. It also has very low distortion characteristics, making it a great choice for use in audio and video circuits.

Working Principle of 4470-48G

The working principle of a fixed inductor is relatively simple. It works by utilizing the basic properties of magnets and electrically conductive materials. When current passes through the wire of an inductor, a magnetic field is generated around the wire. This magnetic field interacts with the core of the inductor which results in a voltage being induced in the wire. This induced voltage opposes the original current, creating what is known as an “inductive voltage drop.” This voltage drop results in the inductor’s ability to control or modify the flow of current.

The 4470-48G is a self-shielding fixed inductor, which means that its construction is designed to suppress electromagnetic and radio frequency interference. It is also designed to withstand high amounts of current, making it well-suited for power applications.

Conclusion

The Bourns 4470-48G fixed inductor is a reliable and versatile component, well-suited for use in a variety of applications. Its self-shielding construction makes it suitable for use in power circuits as well as high-frequency audio and video circuits. Its operating temperature range and low distortion characteristics make it an ideal choice for medical, automotive, and consumer applications.
