RFIs and EMI is a major concern for both consumers and the industries. As technology progresses, more and more products radiate a large amount of EMI. In order to prevent EMI from interfering with other signals, RFIs and EMI Shielding and Absorbing Materials are often used.

3M CN3490 7.25" X 1.25"-25 is a shielding and absorbing material designed to reduce the levels of EMI that electronics produce. It is designed to be highly conductive and provides a good shielding effect, reducing EMI to a level sufficient for most applications. Additionally, its perforations provide an escape route for the ambient heat generated by electronics, thus lessening the risk of overheating.

The working principle of 3M CN3490 is quite simple. It works by forming a conductive layer between the source of EMI and the rest of the environment. This layer of conductive material works to limit the spread of the EMI waves, preventing them from reaching other electronic equipment or reception devices. The conductive material also serves as a absorber of EMI, preventing it from being reflected back to the source.

The application field of 3M CN3490 is wide and varied. As it is designed to reduce EMI, it is often used in electronic devices, such as computers, phones, and other communication devices. It is ideal for use in residential and commercial buildings, allowing electronics to work properly without interfering with other signals. Additionally, 3M CN3490 can be used to protect sensitive equipment, such as medical devices, from the interference of outside EMI.

3M CN3490 is a versatile shielding and absorbing material. It is designed for effective EMI reduction, and its conductive layer and perforations offer additional protections from heat buildup. With its wide application field, 3M CN3490 is an invaluable material for RFIs and EMI shielding and absorbing.
