Fixed Inductors

Fixed inductors are electrical components that store energy in the form of magnetic fields when electric current is conducted through them. The LBR2012T220K is one such fixed inductor, widely used in communication and industrial electronics. This article provides an overview of the LBR2012T220K’s application fields and working principle.

Application Fields

The LBR2012T220K is a high quality, low cost, surface mount power inductor used in many types of communication and industrial electronics. It is designed for use in high frequency applications where extremely low noise performance is required, such as in telecommunications and data communications equipment. The LBR2012T220K is also a reliable power inductor used in switching power supplies, dc-dc converters, and voltage regulator circuits.

Working Principle

Fixed inductors work on the principle of Lenz’s law, which states that an induced electric current in an inductor will always oppose the change in current that created it. When electrical current is conducted through a fixed inductor, it creates a magnetic field that stores energy. When the current is removed, the magnetic fields slowly decay and the stored energy is released. This process, known as the inductance, is used to create regulated power outputs for various types of electronic devices.

Advantages and Disadvantages

The primary advantage of the LBR2012T220K is its exceptionally low radiated noise performance. This is due to its high quality construction and low signal losses. Additionally, the device is designed to operate reliably in a wide variety of environmental temperature ranges, which allows it to be used in a variety of industrial and outdoor applications. One disadvantage is its size, which is relatively small when compared to other fixed inductors.

Conclusion

The LBR2012T220K is an ideal choice for applications requiring low noise, high performance, and dependable operation. Its small size makes it an ideal solution for complex designs. While it has some minor drawbacks, such as its size, its benefits far outweigh its drawbacks. For this reason, it remains one of the most popular fixed inductors available on the market today.
