Fixed inductors are electrical components specifically designed to store energy in the form of a magnetic field, and are an essential component in many different types of circuits. One of the most common types of fixed inductors is the SP1008R-821K, which is a high frequency inductor designed for low profile surface mount applications. In this article, we will discuss the application fields and working principles of the SP1008R-821K fixed inductor.

What is the SP1008R-821K Fixed Inductor?

The SP1008R-821K is a high frequency surface mount fixed inductor which is designed to reduce land area while still providing high frequency performance. It consists of a winding of copper wire embedded in a ferrite core, which is then encapsulated in a polystyrene body. The body of the inductor is just 1.07mm in height and the overall size of the device is 10mm x 8mm. The typical inductance value rang of 4.7uH to 10uH with an operating temperature range of -40℃ to +125℃.

Applications of the SP1008R-821K Fixed Inductor

The low profile design and high frequency performance of the SP1008R-821K makes it an ideal choice for many different types of applications. For example, the device can be used in mobile phones for RF and antenna applications, as well as in products such as laptop computers, automotive electronics and more. Furthermore, the fixed inductor can also be used in a wide range of applications involving switching converters, inverters, power supplies and the like. This makes it one of the most versatile fixed inductors available.

Working Principles of the SP1008R-821K Fixed Inductor

The principle of operation of the SP1008R-821K fixed inductor is similar to that of any other inductor. When an alternating current (AC) passes through the inductor, a magnetic field is created and is stored in the inductor. When the AC is interrupted, the stored magnetic field causes a voltage to be induced across the inductor, which is then used to continue the current flow. This is how the inductor is able to store energy and act as a filter or noise reducer, thus making the SP1008R-821K fixed inductor an important component in many different types of circuits.

Conclusion

In summary, fixed inductors like the SP1008R-821K are invaluable components in various applications. From mobile phones and other consumer electronics to power supplies and inverters, the SP1008R-821K can be used in a variety of devices. Its high frequency performance and small form factor make it an ideal choice for low profile surface mount applications. Additionally, by understanding how the fixed inductor works, design engineers can take full advantage of the SP1008R-821K and its abilities.
