In the world of electrical engineering and electronic equipment, noise cancellation and shielding are paramount to device operation. RFI and EMI Shielding and Absorbing Materials are important tools used to accomplish this. This article will discuss the 78085100 application field and working principle to provide a better understanding of these methods.

What is RFI and EMI Shielding and Absorbing Materials?

RFI and EMI Shielding and Absorbing Materials refer to any material type used to reduce or prevent electromagnetic radiation interference (EMI) or radio frequency interference (RFI). Shielding methods are used to block electromagnetic waves from interfacing with the environment, or at least curtail their interaction. On the other hand, absorbing methods are used to assimilate the noise and remain unaffected by their surrounding environment. Shielding and absorption materials are typically used together to effectively manage both instances.

Application Field

The 78085100 shielding and absorption material of RFI and EMI can be used on different equipment and systems, such as aerospace, automotive, communication, computers, and consumer electronics. Aerospace systems often require a light yet effective shielding and absorption material so as to maintain light weight and energy efficiency. Automotive requires light materials as well, but noise cancellation is needed throughout its interior to reduce road noise. Communication, computers, and other electronic systems need to remain protected from static discharge and external noise in order to maintain performance.

Working Principle

When it comes to shielding materials, there are two processes to be aware of: reflection and absorption. Reflection occurs when incoming electromagnetic waves bounce off the surface of the shielding material and return in the same direction it came from. This is an effective method for eliminating most of the interfere signals. Absorption is slightly different. In this process, the source of the signal is degraded by the material and then unable to be transmitted. It was previously mentioned that shielding and absorption are typically used together to eliminate noise. While the reflection part represents the shielding element of the material, the absorbent side is the absorbing component.

Conclusion

In conclusion, the 78085100 application field and working principle of RFI and EMI Shielding and Absorbing Materials is crucial to any electrical system. Through this material, it is possible to eliminate EMI/RFI interference by reflecting and absorbing electromagnetic signals. Shielding materials often need to be employed in various types of applications, such as aerospace, automotive, computers, and communication. Additionally, the working principle of shielding involves reflecting and absorbing electromagnetic energy to eliminate external noise.
