RFI and EMI - Shielding and Absorbing Materials are used to prevent the transmission or reception of electromagnetic signals in order to protect electronic and electrical systems from interference. The 3M CN3490 2” X 6”-25 Shielding and Absorbing Materials is an effective tool that provides shielding and absorbing features for a wide variety of application fields. It is ideal for applications involving electric and electronic equipment, such as antenna and communication systems.

The 3M CN3490 2” X 6”-25 Shielding and Absorbing Materials uses copper foam to enable effective shielding and absorbing performance for electromagnetic interference (EMI) and radio frequency interference (RFI). The copper foam is composed of interconnected, three-dimensional channels. These channels allow for a high density of shields, greater than the average EMI shielding material, thus providing more Efficiency gains and cost savings. The copper foam also reduces the amount of space required for shielding, making it ideal for applications that require dense shielding solutions.

The working principle of the 3M CN3490 2” X 6”-25 Shielding and Absorbing Materials is based on the principle of electromagnetic shielding. The material is composed of a copper-based layer which acts as an electromagnetic barrier, blocking and absorbing EMI and RFI signals. The material helps in isolating electronic devices from heat and pressure while still shielding them from EMI and RFI. It also helps in controlling the amount of energy released by a device, allowing it to be operated safely and efficiently.
