Fixed Inductors encompass a large variety of different types of electrical components. The NRS5040T330MMGJ is one type of fixed inductor that can be used in a variety of applications. This article will provide an overview of its application field and working principle.

Application Field

The NRS5040T330MMGJ is a common-mode EMI filter for differential signal pairs. It is used to clamp common-mode noise from differential signals by providing high-frequency attenuation with a wide frequency range. It is ideal for applications that require EMI filtering in high-frequency, multi-mode, and differential operations. These include automotive, industrial, and telecommunications applications. It also has a low-profile and high-temperature tolerance, making it suitable for portable and high-power applications.

Working Principle

The NRS5040T330MMGJ works by providing a high-frequency attenuation path between two differential signals. This path acts as a filter to reduce common-mode noise. This is done by utilizing two sets of windings which are coupled together. The primary winding is energized with the positive signal while the second winding is energized with the negative signal. The windings are wound with non-magnetic wires in such a way that the two signals interact with each other in an opposing manner. This creates an induced current which acts to cancel out the EMI noise from the two signals.

The NRS5040T330MMGJ also features an integrated capacitance to provide additional suppression of common-mode noise. This helps to ensure that only the desired signal is present. The integrated capacitance is also designed to reduce inter-signal coupling, which further helps to reduce unwanted signal interference. As a result, the NRS5040T330MMGJ is able to provide efficient and reliable EMI filtering for high-frequency, multi-mode, and differential operations.

Fixed inductors are an essential component of any electronic system and the NRS5040T330MMGJ is no exception. This EMI filter provides reliable noise suppression with a wide frequency range and high-temperature tolerance. It is ideal for applications that require EMI filter in automotive, industrial, and telecommunications applications. With its integrated capacitance, it is able to ensure the presence of the desired signals while eliminating unwanted noise.
