3M CN3490 3" X 1.25"-25 is one of the shielding and absorbing materials materials used for radio frequency interference (RFI) and electromagnetic interference (EMI). It is a highly effective material for eliminating unwanted noise in a variety of applications. The material is a combination of foils and adhesive layers which can be used to block and absorb RFI and EMI emissions. This article will discuss the application field and working principle of 3M CN3490 3" X 1.25"-25 as an RFI and EMI shielding and absorbing material.

3M CN3490 3” X 1.25”-25 can be used in various applications, where interference reduction is needed. This includes cell phone towers, antenna systems, radio and broadcasting systems, radar systems, aircraft, marine communication systems, military communication systems, and commercial electronic systems. The material acts as a barrier to reduce the transmission of interference into or out of these systems. In addition, it can be used in high-voltage systems where RFI and EMI can cause problems. It can also be used in automotive applications to reduce interference from electrical engine components.

The working principle of 3M CN3490 3" X 1.25"-25 is mainly based on the reflection and absorption of RFI and EMI. The material consists of multiple layers of foils and materials. The materials used are highly conductive metals, such as copper and aluminum. These metals reflect RFI and EMI back to the source, preventing it from spreading. The materials also absorb RFI and EMI which prevents them from entering the protected area. The layers are designed to work together in an overlapping manner, to ensure maximum efficiency in a range of frequencies. The more layers that are included in the design the better the protection will be.
