3M CN3490 1/2" X 3"-100

RFI and EMI shielding and absorbing materials are essential components of any electronic device. In the case of 3M CN3490 1/2" X 3"-100, this shielding and absorbing material is composed of a combination of nickel-iron (NiFe) and copper-iron (CuFe) alloys. These alloys provide an effective way to shield and absorb electromagnetic interference (EMI) and radio frequency interference (RFI). The material also effectively dissipates heat under high temperatures, making it an optimal choice for a variety of applications.

The NiFe and CuFe alloys of the 3M CN3490 1/2" X 3"-100 can be used in EMI/RFI shielding, absorption, and diffusion applications across various industries. It can be used in consumer electronics applications, such as cable shielding and cellular phones, as well as in automotive and military applications, such as aircraft radar avoidance systems. The material is also ideal for industrial settings, such as factories, where it can help reduce the radiation leakage from high-frequency emissions and provide electromagnetic shielding on sensitive machinery. In medical settings, it can be used to protect sensitive equipment such as ECG monitors and other medical equipment against electromagnetic interference.

The 3M CN3490 1/2" X 3"-100 works by providing three essential functions: shielding, absorption, and diffusion of electromagnetic interference and radio frequency interference. The NiFe and CuFe alloys of the material act as a barrier to block EMI and RFI, effectively preventing external sources of interference from entering the system. These alloys also absorb and reduce the radiation’s power, dissipating the energy and preventing it from reflecting off the surface of the material. Finally, the material diffuses the waves in order to reduce the power even further, thus minimizing the signal strength.

The 3M CN3490 1/2" X 3"-100 is designed for ease of installation, coming in the form of an easy-to-use, pre-cut sheet. The material can be cut and shaped as needed for applications requiring precise fitting or custom designs. It can also be used in combination with other EMI/RFI shielding materials, such as conductive fabrics, foams, and gaskets, allowing it to be used in more advanced applications.

The 3M CN3490 1/2" X 3"-100 is a versatile and durable shielding and absorbing material designed for a diverse range of applications. Its combination of NiFe and CuFe alloys makes it effective at shielding, absorbing, and diffusing EMI and RFI, while its flexible construction allows for easy installation and a wide range of uses. As such, the material is an ideal choice for many different types of applications and settings, from consumer electronics to military systems.
