Fixed Inductors

Fixed Inductors are widely used in various applications such as power management, filtering, and electromagnetic interference (EMI) control. An example of a popular type of fixed inductor is the 1120-331K-RC which has a wide range of applications.

Application Field

The 1120-331K-RC is used in high-current DC-DC application, such as computer applications, automotive power converters, and other DC power sources. Its wide application field makes the 1120-331K-RC suitable for both industrial and consumer applications. Furthermore, it can be used for filtering noise and reducing electrical current ripple in a wide range of applications.

The 1120-331K-RC has an operating temperature range from -20 to +85 degrees Celsius, allowing it to be used in areas with a wide range of environmental temperature conditions (including automotive and electronics). Additionally, the 1120-331K-RC is suitable for harsh environments, as it can tolerate high pressure levels and electromagnetic noise.

Working Principle

The 1120-331K-RC operates on an inductive switching method. It has an inner core around which a wire is wound, thus forming an inductive coil. When electricity is applied to the coil, it creates an alternating magnetic field. This magnetic field interacts with the core, creating a magnetic flux that flows through the outer core, thus producing an output voltage through an inductive system.

The current in the inductive system is determined by three primary factors: the applied voltage, the number of turns of wire, and the physical dimensions of the core. By varying each of these factors, the output voltage can be changed and adjusted. This allows the 1120-331K-RC to be highly adjustable and personalized for different applications and environments.

The 1120-331K-RC also has an external filter which helps reduce peak voltage. The external filter helps reduce the power output of the inductor, resulting in smoother and more efficient performance. It also helps reduce electrical noise, allowing the inductor to operate with less interference from external sources.

Conclusion

The 1120-331K-RC is a popular fixed inductor with a wide range of applications, from power management to EMI control. Its adjustable design and external filter make it suitable for working in harsh environmental conditions, such as automotive applications. Understanding its working principle and factors that affect its output voltage can help users take full advantage of its features.
