Introduction

EMI/RFI filters, also known as LC, RC networks, are widely used for various types of applications, such as industrial automation, medical, communication, and consumer electronics. The NFE61PT680B1H9L is a specific type of EMI/RFI filter, which is designed to reduce electromagnetic interference (EMI), and radio frequency interference (RFI). This article will discuss the application field and working principle of the NFE61PT680B1H9L.

Application fields of the NFE61PT680B1H9L

The NFE61PT680B1H9L EMI/RFI filter is a high-performance, high-reliability filter that has a wide range of applications. It is most commonly used in the industrial sector for industrial automation systems, as well as medical applications such as hospital medical equipment. It is also used in communication equipment and consumer electronics, as well as in applications where high-frequency interference and noise must be kept to a minimum.

Working Principle of the NFE61PT680B1H9L

The NFE61PT680B1H9L filter works on the principle of “impedance attenuation”. This type of filter is designed to reduce EMI/RFI noise by lowering the frequency of interference. The filter works by inserting varying-sized “resistor elements” into the signal line. These resistor elements are designed to reduce the level of interference and absorb energy from both common-mode and differential-mode interference signals. The amount of reduction is determined by the size of the resistor elements and the type of filter selected. The NFE61PT680B1H9L EMI/RFI filter also incorporates an additional feature known as “ground-isolation”. This feature works to reduce any unintentional electrical paths that may be present between the filter and the device being protected from interference. The filter also has a “shielding effect” that helps reduce both common-mode and differential-mode interference at higher frequencies.

Conclusion

The NFE61PT680B1H9L EMI/RFI filter is a high-performance, high-reliability filter, designed to reduce electromagnetic interference and radio frequency interference. It offers superior performance in industrial, medical, communication and consumer electronics applications, where it is able to reduce interference levels by means of impedance attenuation and ground-isolation. The filter also has a shielding effect that helps reduce interference from higher-frequency signals.
