Introduction

RFI and EMI shielding and absorbing materials are widely used in many industries for shielding electronic components from the dangers of electromagnetic interference (EMI) or radio frequency interference (RFI). The EA-TD128-2-24 is one such material, which is a Type 3480 EMI/RFI absorber that offers dual-band shielding performance over a wide frequency band of 30 MHz to 6 GHz. In this article, we will discuss the application field and the working principle of the EA-TD128-2-24 EMI/RFI absorber.

Application Field

The EA-TD128-2-24 material has been designed for use in a variety of industries, including aerospace, defense, automotive, and telecommunications. It is suitable for applications in which EMI/RFI shielding performance is required over a wide frequency range. This could include systems where EMI/RFI shielding is required to protect sensitive components against interference from long-distance signals or signals bouncing off of nearby objects, such as construction sites and buildings.In aerospace, the material is used to protect sensitive guidance systems from the effects of RFI/EMI, reducing the errors caused by interference and thus improving the accuracy of the system. In military applications, the absorber is used to shield sensitive aircraft systems, increasing their reliability and preventing interference from external sources.The EA-TD128-2-24 EMI/RFI absorber is also used in automotive applications, primarily to protect electronic displays, sensors, and systems from the effects of RFI/EMI generated by nearby objects, such as power lines and radio towers. The material is also used in telecommunications systems to shield incoming signals from interference.

Working Principle

The EA-TD128-2-24 material works by absorbing electromagnetic radiation and converting it into heat. The absorber consists of a combination of carbon-based film and synthetic foam, sandwiched between two layers of aluminum foil. This construction creates a conductive barrier that blocks RF interference while allowing the signal to pass through. The carbon film on the inside of the absorber acts as a dielectric layer, absorbing the RF signal and converting it into heat.The EA-TD128-2-24 EMI/RFI absorber also has a combination of high absorption and low reflection coefficients, allowing it to block a wide range of frequencies. This makes it suitable for shielding a wide variety of signals, from short-range signals to long-distance signals.

Conclusion

The EA-TD128-2-24 is a Type 3480 EMI/RFI absorber that offers dual-band shielding performance over a wide frequency band of 30 MHz to 6 GHz. It is used in a variety of industries for EMI/RFI shielding. The material works by absorbing electromagnetic radiation and converting it into heat. It also has a combination of high absorption and low reflection coefficients, allowing it to block a wide range of frequencies.
