Fixed Inductors

A fixed inductor is a type of inductor whose inductance value cannot be adjusted or varied. They come in different shapes and sizes and have a variety of applications. PTHF50-50 is an example of such an inductor. This article will discuss the application field and principle of the PTHF50-50 inductor.

Application field

The PTHF50-50 fixed inductor is designed to be used in DC-DC converters, SMPS, and AC-DC power supplies, making it well suited for various consumer, industrial, and automotive applications. It is used in situations where stable inductor currents are required and can be helpful in smoothing out ripples of current or voltage. It is also well-suited for use in DC-DC conversion because it reduces EMI noise at the input and output ports.

Working Principle

The working principle of the PTHF50-50 fixed inductor centers around the property of inductance. In a fixed inductor, a series of windings are wound around a magnetic core material such as iron, which has the property of having a larger inductance than an air core. These windings form a circuit that presents an inductive reactance that prevents changes in current flow.

Current flowing through the inductor’s windings produces a magnetic field which interacts with the core material, resulting in an inductive reactance. This increases with increasing current and is independent of frequency. The resulting inductive reactance opposed to the flow of AC current and results in a decrease in the peak-to-peak amplitude of the circuit’s output.

The amount of inductive reactance produced by the fixed inductor is determined by the characteristics of its core material, the number of windings and the size of the core material used. The inductor’s inductance is also determined by its core material and the number of turns in the winding. The dimensions of the winding are kept small in order to minimize self-heating and noise. The core material used in fixed inductors provides excellent saturation characteristics and low losses.

Conclusion

The PTHF50-50 fixed inductor is a versatile component that has a number of applications in DC-DC conversion, SMPS, and AC-DC power supplies. It is designed to have excellent saturation characteristics and low losses, and it works by producing an inductive reactance which is determined by the number of windings and the type of core material used. This makes it well suited for a variety of different applications.
