RFI and EMI – Shielding and Absorbing Materials

Electromagnetic interference (EMI) and radio-frequency interference (RFI) are commonly found in electrical and electronic systems due to their emissions of interference waves. These interference waves propagate in different directions and affect the quality of the data or signal being processed in the system. To prevent or reduce the amount of EMI/RFI emitted by a system, it is important to use shielding and absorbing materials to limit the radiation from the device. One of these materials is EA-RF500-24.

EA-RF500-24 is an electrically conductive and radiative attenuating foil that provides shielding against electromagnetic and radio frequency interference (EMI/RFI). It is designed to be used in various applications such as power line, audio line, and antenna line. This material is also suitable for radio frequency isolation (RFI) and electromagnetic radiation control (EMR).

EA-RF500-24 is made of a combination of carbon polymer and aluminum. It has an impedance close to 0 ohms and a resistivity of less than 0.3 ohms per square. This combination of properties makes the material extremely effective at shielding against EMI/RFI. It is also very lightweight and flexible, making it easier to install in various applications.

The working principle of EA-RF500-24 is based on the concept of dissipative shielding. In this type of shielding, the material absorbs the interference energy and converts it into heat which is then dissipated away. This material is designed to provide high performance in both frequency and amplitude, and is capable of providing average shielding efficiency of 80 dB. This makes it suitable for use in applications that require a greater degree of shielding.

EA-RF500-24 is currently used in a variety of applications including power line, audio line, antenna line and radio frequency isolation. In power line applications, the foil acts as a shield between different power lines to reduce the amount of interference. The same principle can be applied to audio and antenna lines where the noise needs to be reduced to ensure a clear sound. Finally, in radio frequency isolation applications, the foil is used to block the transmission of signals from one device to another.

To summarise, EA-RF500-24 is an electrically conductive and radiative attenuating foil that provides shielding against EMI/RFI. It is designed to reduce the amount of interference caused by EMI/RFI in various applications. The material is lightweight and flexible, and has a resistivity of less than 0.3 ohms per square. The working principle of EA-RF500-24 is based on dissipative shielding, and it is capable of providing average shielding efficiency of 80 dB. This material is currently being used in power line, audio line, antenna line and RF isolation applications.
