The application field of 3M CN4490 1.5" X 6"-100 includes automotive electronics, aerospace components, medical devices, RF and EMI shielded enclosures, radio frequency identification (RFID) tag readers, and other RF and EMI sensitive applications. Additionally, it can be used to make gaskets, seals, and groundplanes which are used for absorbing and shielding high frequency interference.

The working principle of 3M CN4490 1.5" X 6"-100 is based on the principle of electrical shielding. It works by creating a conductive layer which prevents external electromagnetic radiation from entering or exiting the protected environment. This is achieved by using an electrically conductive material such as copper which can act as an effective shield against interference. The material also has the ability to absorb and disperse the energy of the incoming RF signals, effectively blocking them from entering the protected environment.

The other main feature of 3M CN4490 1.5" X 6"-100 is its flexibility. This ensures that the shield is able to conform to the contours of the protected environment, providing an effective barrier against EMI and RFI. It is also highly resistant to physical damage, ensuring its long-term performance.

Overall, 3M CN4490 1.5" X 6"-100 is an ideal shielding and absorbing material for a broad range of electronic applications. It is highly effective at preventing signal loss and reducing electromagnetic interference. Its flexibility and durability make it ideal for use in tight spaces and harsh environments. Finally, its low electrical resistivity and excellent damping properties make it an ideal choice for shielding sensitive electronics from external EMI and RFI radiation.
