Radio frequency interference (RFI) and electromagnetic interference (EMI) are common problems encountered in electronic systems. RFI and EMI can cause malfunctions in equipment, introduce noise into systems, and adversely affect data transmission and reception. This makes it important to understand the characteristics of shielding and absorbing materials, and how they can be used to mitigate the effects of RFI and EMI.

The RT-2119/1167 is an example of a type of shielding and absorbing material used both to reduce the level of incoming radio waves and protect against the emission of RF energy. It is primarily composed of copper, tin, and zinc, with a protective coating to reduce corrosion and interconnect oxidation. This material is typically used in commercial and military applications, such as in the construction of aircraft, where electromagnetic radiation must be controlled. It is also used in industrial applications, such as telecommunications equipment, to protect against RFI and EMI.

The material\'s shielding and absorbing properties are determined by its dielectric constant and dielectric loss. The dielectric constant (K), also known as the relative permittivity, is a measure of the electrostatic field created by material and its ability to store electric charge. The dielectric loss (Q) is a measure of the material\'s ability to dissipate electric fields.

RT-2119/1167 has a dielectric constant of 3.5-3.95 when measured at 500 MHz and a dielectric loss of 0.008-0.01 at the same frequency. This indicates that the material is highly effective at absorbing incoming radio waves and preventing them from entering a system, as well as blocking the emission of RF energy. Additionally, the material is highly resistant to corrosion and oxidation, making it suitable for use in high-vibration and/or temperature environments.

The RT-2119/1167 is commonly employed in the construction of RF shields and filters, which allow certain frequencies to pass while blocking unwanted RF signals. It is also used as a lining to protect against RF interference in electronic enclosures, as well as in grounding and bonding systems to reduce the risk of EMI. The material can also be used in the construction of EMI-shielded cable assemblies, where it provides protection against cable-induced interference.

In summary, the RT-2119/1167 is a type of shielding and absorbing material designed to reduce the levels of incoming radio waves and protect against the emission of RF energy. It has a high dielectric constant and low dielectric loss, making it an effective solution for mitigating the effects of RFI and EMI in a variety of applications. It is commonly used in the construction of RF shields and filters, in lining electronic enclosures, and in grounding and bonding systems.
