Fixed Inductors

Inductors are passive components that store energy in the form of a magnetic field and oppose changes in current, thereby limiting voltage gain and maintaining a constant current. Fixed inductors are usually used in applications where the inductance needs to remain constant and are commonly used in RF circuits where precise control over the inductance is necessary. The PM428S-2R7-RC is a type of fixed inductor and has a wide range of applications.

Applications of PM428S-2R7-RC

The PM428S-2R7-RC is primarily used in RF applications such as cellular phones, satellite antennas, and GPS systems. It is well suited for RF applications due to its stable inductance, low DCR, high current rating, and wide frequency response. The inductor can also be used in power supply filtering circuits, switching power converters, and DC/DC converters. It is also popular in automotive, industrial, and medical applications where its robust construction and ability to tolerate higher temperatures make it suitable for use in harsh environments.

Working Principle of PM428S-2R7-RC

The PM428S-2R7-RC is a type of fixed inductor which utilizes a ferro-magnetic core wrapped with an insulated magnetic wire. This arrangement creates a magnetic field around the core, which captures energy from the current passing through the inductor and stores it in the form of a magnetic field. This process is known as inductance. As current is passed through the inductor, the stored energy opposes the current, creating a voltage drop across the inductor. This voltage drop is called the counter electromotive force (back EMF) and helps to limit the current draw. The inductance of the PM428S-2R7-RC can be adjusted by changing the size and shape of the core or by adding additional windings to the inductor.

Conclusion

The PM428S-2R7-RC is a type of fixed inductor which is suitable for a wide range of applications. Its low DCR, high current rating, and wide frequency response make it ideal for use in RF circuits, while its robust construction and ability to tolerate higher temperatures make it suitable for use in harsh environments. The inductor works by creating a magnetic field around a ferro-magnetic core which captures energy from the current passing through the inductor and stores it in the form of a magnetic field. The inductance can be adjusted by changing the size and shape of the core or by adding additional windings to the inductor.
