The 3M CN3190 1/2" X 3"-100 shielding and absorbing material is a versatile and cost-effective solution for those requiring effective and efficient electromagnetic interference (EMI) and radio frequency interference (RFI) shielding and absorption. Its application field extends to a variety of sectors, including military, aerospace, commercial, automotive and medical. The material is made using a unique combination of conductive non-woven fabric and particulate-filled EMI shielding layers.

The shielding material works by blocking or attenuating the propagation of electromagnetic radiation through its soft magnetic sheets, which are composed of ferrite particles, carbon, graphite and other materials. The particulate-filled EMI shielding layers act to further reduce the radiation, while the flexible non-woven fabric ensures the material conforms around components and circuitry. The material can be easily sewn or applied onto other components such as chassis frames, and it can be applied with adhesives, such as water-based adhesives, for fastening onto surfaces.

As the material is lightweight and easily applied, it can be used in a variety of environments and scenarios, including on moving components and military and civilian aircraft. The 3M CN3190 material is RoHS 2 certified and has UL 94 HBI flame retardant properties. It is available in a variety of sizes and is easy to cut into the right shape for whatever application.

The primary application of the 3M CN3190 1/2" X 3"-100 shielding and absorbing material is to provide shielding from unwanted electromagnetic radiation, as well as from RFI. As it is flexible and lightweight, it can be quickly and easily applied to enclosures and electronic components. It also provides EMI shielding for wires and cables passing through the fabric.

The working principle of the CN3190 material relies on its ability to absorb and block unwanted EM radiation. The most effective way of blocking EM radiation is to use materials that conduct electricity and are also strongly magnetic. The CN3190 material does this through its combination of soft ferrite magnetic sheets and particulate-filled EMI shielding layers, which are able to absorb and block the EM radiation, thus protecting the components within. The non-woven fabric also helps to conform the material around components and other surfaces.

The 3M CN3190 1/2" X 3"-100 shielding and absorbing material is suitable for a wide range of applications, from industrial and military, to automotive and medical. Its flexible form factor and ease of use makes it an ideal solution for those looking for effective EMI and RFI shielding and absorption. With a range of sizes and configurations available, the 3M CN3190 material is well-suited to a variety of tasks and can easily be applied using adhesives or sewn onto components.
