In the world of technology, shielding and absorbing materials play an essential role in the implementation of radio frequency interference (RFI) and electromagnetic interference (EMI) reduction systems. RFI and EMI materials reduce the interference between different kinds of electronic systems by providing insulation from electromagnetic waves and/or absorbing the radiation frequencies, thus limiting the transmission of potentially damaging signals. 3M CN3490 0.75” X 1.5”-250 is an RFI and EMI shielding and absorbing material with multiple uses in many industries.3M CN3490 is among the top performing materials in terms of shielding and absorbing performance, with a very low ‘leakage ratio’ in the frequency range from 3MHz to 3GHz. It is a highly advanced material, featuring a two-dimensional construction which unites a conductive layer with an absorbent medium between two non-conductive layers. This composite material also provides excellent flexibility and stability, making it suitable for a great variety of applications and greatly enhances its efficiency in eliminating interference in the frequency range from 3MHz to 3GHz.The most typical application of 3M CN3490 is in static-sensitive enclosed electronics. It is designed to create a fully enclosed ‘faraday cage’ of protection in the form of a shielding enclosure, which helps to reduce the possibility of microscopic particles entering and interfering with the operation of the electronic components. It can also be used to shield sensitive electronic devices in mobile devices, automotive, aviation, and military applications, as it provides the same degree of protection.3M CN3490 can also be used to absorb the interferences in electronic systems which employ wireless technology such as Wi-Fi and Bluetooth. The material has excellent absorption properties over a wide range of frequencies, and can be used to reduce the interference generated by these signals.The material is also suitable for applications such as Industrial Control Systems (ICS), as it helps to ensure high levels of reliability and accuracy in the system’s operation. In addition, its excellent flexibility and resistance to chemical and thermal ageing make it perfect for use in industrial environments, which are often subject to extreme temperatures and humidity. It also provides insulation against static electricity, thus reducing the risk of equipment failure or system shutdowns.3M CN3490 is also suitable for use in medical instruments and equipment, as it provides excellent shielding against external interference, while maintaining the highest level of safety for the patient. The material can also be used for medical implants, such as pacemakers, which require the highest degree of shielding against any external signals.Overall, 3M CN3490 is a highly advanced and efficient shielding and absorbing material, with a great variety of applications in the industry ranging from wireless communication systems to industrial automation to medical implants. It has excellent shielding capabilities in the frequency range from 3MHz to 3GHz, as well as excellent absorbent and insulation properties. Its two-dimensional construction provides enhanced flexibility and stability for different applications, making it one of the top performing materials in the RFI and EMI shielding and absorbing market.
