RFI and EMI - Shielding and Absorbing Materials, such as the 3M CN4490 8" X 10.5"-25, are materials that act to shield against or absorb electro-magnetic interference (EMI). EMI is a form of electromagnetic radiation that can cause interference in electronic systems, such as computers and cellular phones, resulting in a degraded performance and poor quality signal transmission.

The 3M CN4490 8" X 10.5"-25 is a highly effective EMI Absorbing and Shielding material that provides up to 50 dB of attenuation up to 2GHz. It is designed for both indoor and outdoor applications, and is suitable for use in enclosures and on exposed surfaces. It is an ideal solution for the shielding of electronic equipment from RF and EMI interference sources such as radio transmitters, mobile phones, and power lines.

The 3M CN4490 8" X 10.5"-25 is a specially engineered carbon backbone structure designed to absorb and dissipate EMI energy over a large range of RF frequency spectrum. The design of the CN4490 allows for excellent shielding effectiveness while maintaining minimum physical bulk and weight. The materials come with pressure sensitive adhesive backing for easy application and installation.

The material also features a scratch-resistant, semi-gloss finish that allows it to be used in difficult-to-reach areas such as tight engine compartments or recessed areas. Furthermore, the CN4490 is waterproof, weatherproof, and UV resistant, providing superior durability even in harsh environments.

The working principle of the 3M CN4490 8" X 10.5"-25 is based on the fact that when electromagnetic energy comes into contact with the material, it is absorbed and dissipated by the material as heat. This makes it an efficient and cost-effective solution for reducing RF and EMI interference in a variety of applications.

The 3M CN4490 8" X 10.5"-25 is an ideal solution for the shielding and absorption of electromagnetic interference. Its high shielding effectiveness, ease of installation, and durability make it an ideal solution for a wide range of applications. Whether used in an industrial facility or in a consumer product, the 3M CN4490 8" X 10.5"-25 offers superior EMI shielding and absorption.
