RFI and EMI - Shielding and Absorbing Materials

RF shielding and EMI absorption materials have become increasingly important in today’s electronics as the advent of wireless communication brings a growing variation of RF frequencies and signals. Efficient shielding and absorption of these signals is needed to protect sensitive equipment and personnel from the damaging effects of electromagnetic interference (EMI) and radio-frequency interference (RFI).

EFG(02)-240X240T0800 Application Field

The EFG(02)-240X240T0800 shielding and absorption material is designed to meet this need. This material is a highly flexible and lightweight aluminum/glass fabric composite, proven to provide superior shielding and absorption performance. It can be installed almost anywhere, including cramped spaces, with its thin, space-saving profile. It is a widely used material in various industrial and commercial applications such as automotive EMC systems, electronic instrumentation, defense systems, household video products, and more.

Working Principle

The working principle of the EFG(02)-240X240T0800 shielding and absorption material is to absorb electromagnetic waves in the surrounding environment and reduce the noise emitted by the electromagnetic interference sources, thus improving the quality of signal transmission. It also reflects the electromagnetic waves back to their source and thus prevents them from entering the device.

This material is designed for operating temperature of -50 to 200°C and has a thermal expansion coefficient of 59ppm/°C. It is equivalent to MIL-STD-188-125 Type 1 and meets EMI/RFI requirements of MIL-STD-225-25 as well. It is also available in various sizes, colors, and densities for different applications.

Conclusion

In conclusion, the EFG(02)-240X240T0800 shielding and absorption material is a highly effective solution for providing superior shielding and absorption performance against electromagnetic interference. With its thin, space-saving profile, it can be installed almost anywhere and is widely used in various industrial and commercial applications. It is designed to meet the MIL-STD-188-125 Type 1 requirements and meets EMI/RFI requirements of MIL-STD-225-25 as well.
