RFI and EMI - Shielding and Absorbing MaterialsThe 3M CN3190 4" x 1.25" - 25 is one of the most advanced shielding and absorbing materials available on the market today. This advanced material utilizes a combination of superior materials and innovative technology to create a highly efficient product. In addition to superior EMI/RFI shielding capabilities, the CN3190 can also be used for reducing noise, improving mechanical strength, and providing an aesthetically pleasing appearance.The 3M CN3190 is composed of a non-metallic core with a conductive composite coating. This material is excellent for shielding against electromagnetic interference (EMI) and radio-frequency interference (RFI). The composite coating consists of two layers: The first layer is an electrically conductive layer that serves as the EMI/RFI shield, and the second layer is a static dissipative layer which absorbs some of the energy of an applied electromagnetic wave. This combination of layers helps provide multi-directional protection and increased efficiency.The key application area of the 3M CN3190 is in the field of telecommunications. It is ideal for use in modem, fax, and cell phone shielding applications. The composite structure of the material makes it an ideal choice for shielding against signal interference. Its multi-directional characteristics make it an excellent candidate for reducing interference from adjacent cables, equipment, and antennas.When used in cable shielding applications, the CN3190 helps prevent radiated energy from escaping through the cable insulation. This can be critical for the performance of communications systems as leakage from cables can cause interference to other nearby cables or equipment. The CN3190 offers superior flexibility and conformability while also providing excellent electrical and mechanical protection.The 3M CN3190 can also be used to absorb electro-magnetic radiation in a variety of industrial and commercial applications. It is effective for uses such as radiation masking, EMI filtering, and shielding against high-frequency energy leakage. In medical environments, it can be used to reduce the amount of radiation emitted from high-powered medical equipment.In summary, the 3M CN3190 is an advanced shielding and absorbing material that offers superior shielding effectiveness and excellent electrical and mechanical protection. It is ideal for a variety of applications including telecommunications, cable shielding, and EMI/RFI protection. The ability to absorb electro-magnetic radiation makes it an excellent choice for medical and industrial applications. This advanced material can be used to improve the performance of any communications system.
