Fixed Inductors

Fixed inductors, also referred to as "chokes," are passive electronic components that store energy in the form of a magnetic field. Fixed inductors can be used for a variety of applications, including signal conditioning, voltage regulation, noise filtering and antenna tuning, among other uses. One example of a fixed inductor is the PM74SH-271M-RC.

PM74SH-271M-RC Application Field and Working Principle

The PM74SH-271M-RC is a surface-mount type inductor with a rated current of 4.7 A. It is made up of a cylindrical core coated with insulating and magnetic materials. The core is surrounded by a copper-clad winding that is held in place by a plastic framework. The PM74SH-271M-RC is used in many common applications, including power supply filters, multi-voltage circuits, and RF systems.

The PM74SH-271M-RC inductor works on the principle of self-induction, whereby a current passing through a wire coil produces a magnetic field within the coil. As the coil cuts the flux lines of the magnetic field, an emf is induced within the coil. The more turns within the coil, the greater the induced voltage. The PM74SH-271M-RC inductor is capable of filtering noise and high-frequency signals, and is also effective in regulating voltage.

The PM74SH-271M-RC inductor can also be used for tuning antennas and other systems that require precision matching of their antenna elements. By adjusting the inductance of the PM74SH-271M-RC inductor, the antenna can be tuned to the exact desired frequency. The PM74SH-271M-RC inductor also works in multiple voltage circuits, helping to reduce EMI noise and stabilize power delivery.

The PM74SH-271M-RC inductor is a durable and reliable electronic component, with a favorable temperature coefficient that remains low during application. Furthermore, it has a low profile design and is resistant to moisture and corrosion, making it suitable for use in a variety of environments. The PM74SH-271M-RC inductor is also easy to install, and can be used in both through-hole and surface-mount applications.

Conclusion

The PM74SH-271M-RC is an example of a fixed inductor that is widely used for noise filtering, voltage regulation, antenna tuning, and a range of other applications. Its high-performance properties, such as its low-profile design, temperature coefficient, and durability, make it a very attractive product for many applications.
