Electromagnetic interference (EMI) and radio frequency interference (RFI) are two forms of electrical disturbances that are generated by electrical equipment and transmitted through radio waves. In order to prevent these disruptive forces from affecting the performance of sensitive electronic equipment, EMI/RFI filters are deployed. An application field and working principle of 51-359-051 EMI/RFI filters, or LC/RC networks, will be discussed in this paper.

LC/RC networks are extensively used in a wide variety of applications. Since they are constructed with a combination of inductors and capacitors, they are usually quite compact and can be used to filter out any unwanted EMI/RFI signals. The inductors act as low pass filters, while the capacitors act as high pass filters. By utilizing both, an LC/RC network can provide a strong signal rejection across a wide frequency range. This makes them perfect for use in many different industries such as military, aerospace, automotive, telecom, internet, healthcare, and consumer electronics.

The working principle of an LC/RC network is quite simple. The electrical circuit consists of an AC voltage source, two capacitors, and two inductors. Upon application of the AC voltage, the two capacitors act as series and parallel connected high frequency pass filters while the inductors act as series and parallel connected low frequency pass filters. The circuit is designed such that any unwanted signals, having a frequency outside of the accepted bandwidth, will be rejected. The desired signals, on the other hand, will pass through the LC/RC network.

In order to facilitate better signal filtering performance, the 51-359-051 EMI/RFI filter utilizes a design that features many separate LC networks connected in parallel with each other. The filter also features an improved design structure that achieves excellent rejection performance across the whole frequency range. This makes it ideal for use in applications requiring high performance EMI/RFI filtering.

It is also worth noting that the 51-359-051 EMI/RFI filter is designed to be highly rugged and can withstand extreme environmental conditions. This makes it perfect for harsh applications such as those found in military and aerospace applications. The filter also has a wide temperature range and can withstand temperatures up to 180°C.

In conclusion, the 51-359-051 EMI/RFI filter is a perfect solution for applications requiring strong signal rejection across a wide range of frequencies. The filter utilizes an advanced design that provides excellent signal filtering performance across the entire frequency range, while also being highly rugged and capable of withstanding extreme environmental conditions. This makes it ideal for use in applications requiring highly reliable EMI/RFI filtering performance.
