Fixed inductors are components with two or more nodes that store electrical energy in the form of magnetic fields. Inductors are used in different types of electrical circuits, primarily to filter signals, reduce ripple, and increase switching speeds. In addition, the use of fixed inductors can also help reduce the cost and complexity of a particular system. The 1840R-11K is an example of such an inductor, with an application field and working principle that warrant further discussion in this article.

The 1840R-11K is designed to be used in unipolar switched mode applications, such as point of load DC to DC converters and motor drive systems. This particular inductor is able to provide the necessary inductance levels such that the power system can deliver steady energy to the load. Its size makes it ideal for compact designs where space is limited.

The 1840R-11K has a patented design that helps ensure safety and reliability in conditions involving high RF noise, such as a high-temperature environment. The inductor is made from two ferrite cores, and is rated to have a maximum current rating of 11A. The metallic shield ensures high shielding effectiveness, and the inductance characteristics of the 1840R-11K remain the same over a wide frequency range, making it suitable for a variety of applications.

The working principle of the 1840R-11K is fairly straightforward. When an alternating current is applied, the core material of the inductor converts the electrical signal into a magnetic field. This magnetic field creates a circulating eddy current inside the inductor, and this circulating current creates a resistive magnetomotive force (MMF) in the core. The MMF opposes the current, and the combination of the current and MMF produces a back EMF, which helps to regulate the current.

In addition to the 1840R-11K, there are other types of fixed inductors available, each offering their own set of benefits. Depending on the application, it is important to choose the correct inductor as it can significantly enhance the performance of the system. By selecting the right inductor, engineers can be sure that the product applied will deliver the expected performance and will have the desired reliability.

Overall, fixed inductors like the 1840R-11K provide many benefits to both the consumer and the professionals using them. Their size and efficiency make them ideal for certain applications, while their ability to regulate the current helps increase the longevity of the device. By understanding the application field and working principle of the 1840R-11K, engineers can confidently design and deploy the correct inductor for their specific requirements.
