Fixed Inductors are electrical components that store energy in the form of magnetic fields, which makes them especially useful in applications that require a fixed amount of energy in order to operate. Among these components one of the most common ones is the SRR4028-120Y, an industrialized fixed inductor which has features that makes it ideal for space-saving designs and high-frequency applications. The following will discuss its application fields and working principle.

Application Fields

The SRR4028-120Y Inductor is quite versatile and can be used in a variety of applications. One of its main uses is in filters, by either working as an input filter in power supply units or as an output filter to reduce emissions. It is also used as an inductive load for line regulation and in coupled inductors for switching regulators. Furthermore, it proved to be durable and reliable in impedance matching networks or radio-frequency shielding applications.

Working Principle

The SRR4028-120Y fixed inductor works in a similar fashion to its adjustable inductor counterparts, as it responds to the increase in current by storing energy in the form of a magnetic field. The inductance of these components is highly correlated to the core material, the shape of its magnetic core, number of turns in the magnetizing coil, and the size of the associated components when working in electric circuits. When current flows through a fixed inductor, its flux coils only experience a minimal amount of flux, making them one of the most efficient inductors available in the market.

The characteristics of the SRR4028-120Y are especially useful towards high-frequency applications, as evidenced by its physical properties such as a low magnetic core loss and high-saturation current. It also has a “T” curie temperature which allows them to work reliably at different temperatures, making them a good every-day solution for fixed inductor applications. As the frequency of the current can reach up to 1.5MHz, their design features permit them to be quite robust in terms of switching current.

In addition, the SRR4028-120Y has been designed to be as efficient and space-saving as possible. Their compact size demands less room and they come in surface mount packages, making them a good solution for PCBs. A thick, tinned copper exterior promises high corrosion resistance. All of these characteristics combined make them one of the most suitable components for reasonably priced, fixed inductor applications.

To conclude, the SRR4028-120Y fixed inductors are highly versatile components which prove to be useful in a variety of applications. Their efficiency, space-saving design and ability to withstand high frequencies make them one of the most robust and reliable fixed inductors available. Their ability to store energy in the form of a magnetic field also makes them great for adapting to voltage changes, ensuring high performance for the respective application.
