3M CN3490 1” X 8”-100 is a shielding and absorbing material designed to protect sensitive electronic components from electromagnetic interference (EMI) and radio frequency interference (RFI). It is made from a nickel-coated polyester film with an aluminum/copper backing and an acrylic adhesive, providing outstanding flexibility and durability. It is extremely lightweight and has excellent conformability.

This shielding and absorbing material can be used in a wide range of applications, including automotive, medical, telecom, computer, industrial automation, and aerospace. It is suitable for use on components with complex shapes and tight clearances, and has an excellent performance when installed in high-vibration environments. The material offers high performance EMI/RFI protection, shielding effectiveness up to 80 dB, and a resisting power up to 1800V peak-to-peak.

The working principle of 3M CN3490 1” X 8”-100 is simple but efficient. The material works by reflecting and absorbing electromagnetic waves that would otherwise interfere with the electronic components. It forms an electrostatic shield which blocks the electrical signals that would otherwise contaminate the internal environment. This helps ensure that components are not affected by electromagnetic or radio frequency interference.

The material also has excellent flexibility and conformability, which allows for it to be installed in tight, complex shapes and clearances. This helps to ensure full coverage and protection, ensuring maximum EMI/RFI shielding for the components. The material can also withstand high vibration environments, making it perfectly suited for use in automotive, aerospace, or industrial automation applications.

3M CN3490 1” X 8”-100 is an excellent shielding and absorbing material for use in EMI/RFI applications. It provides excellent shielding performance, has excellent conformability and flexibility, and can be used in high vibration environments. Its simple but effective working principle makes it an ideal choice for protecting sensitive electronic components from EMI and RFI.
