RFI and EMI - Shielding and Absorbing Materials are used to reduce electromagnetic interference (EMI) and radio frequency interference (RFI) from electrical and electronic equipment. 3M CN3490 0.5" X 8"-250 is one example of such a material, which is used widely in a variety of applications. In this article, we\'ll look at the application field and working principle for 3M CN3490 0.5" X 8"-250.

Application Field

3M CN3490 0.5" X 8"-250 can be used in a variety of scenarios where a RFI or EMI attenuation material is needed. It is suitable for both indoor and outdoor use, and can be used in military, aerospace, automotive, and other electronic systems. It effectively shields against all types of electrical noise, including Broadband and Narrowband. It also provides an effective means of absorption against spurious Radio Frequency signals.

In addition to its use in shielding and absorbing materials, 3M CN3490 0.5" X 8"-250 is also used for strain relief in flexible flat cables, multi-conductor cables and round cables, as well as in electronic packaging. It can also be used to attenuate unwanted signals from a variety of sources, including power transmission lines, radios, and cell phones.

Working Principle

3M CN3490 0.5" X 8"-250 is designed to reduce the level of RFI and EMI in sensitive applications. It works by absorbing, reflecting, and dissipating electromagnetic fields. It works by converting the incoming electric and magnetic fields into a form that can be safely dissipated as heat. It absorbs the energy of the EMI/RFI signal, and then gradually releases it back into the surrounding area as heat. It also creates a Faraday cage that effectively shields against all types of electrical noise.

3M CN3490 0.5" X 8"-250 is also designed to allow for flexibility in its application. It can be cut and customized to fit the specific area that needs to be shielded. It can be used with other 3M products, such as 3M EMI/RFI Shielded Cables and 3M Electromagnetic Absorption Tape. It can also be used with traditional metal-shielding materials, such as copper, stainless steel, and aluminum.

3M CN3490 0.5" X 8"-250 is extremely effective in reducing EMI and RFI. It is applicable to a wide range of applications, and provides flexibility in its use. Its ability to absorb, reflect, and dissipate electromagnetic fields makes it the ideal choice for shielding and absorption materials.
