RF Interference (RFI) and Electromagnetic Interference (EMI) are common problems that can affect the proper electrical function of a device. There are a number of ways to mitigate the effects of these types of interference, with shielding and absorbing materials among the most common solutions. 3M CN3490 2" X 4" 25 is one such material, designed to shield and absorb EMI to ensure proper device operation.

3M CN3490 2" X 4" 25 is a water-resistant shielding material designed to provide outstanding protection against a broad range of radio and microwave frequencies. It is composed of a conductive aluminum/zinc alloy layer with a viscoelastic elastomer around it to provide a barrier against the full range of interfering energies. In addition, 3M CN3490 2" X 4" 25 is coated with a pressure-sensitive acrylate adhesive to provide an easy and reliable installation.

The key to using 3M CN3490 2" X 4" 25 effectively is to understand its working principle. The shielding material functions by reflecting and absorbing EMI before it reaches any underlying components of a device. This is accomplished by having a conductive layer that absorbs and disperses interfering electric signals, while the viscoelastic elastomer functions as a barrier to reflect and absorb the majority of incoming EMI. The adhesive helps to ensure that the material is firmly attached to the device, enabling it to do its job effectively.

3M CN3490 2" X 4" 25 is a versatile shielding material, and its application fields are numerous. It can be used to effectively shield all types of electronic components, devices, and assemblies, including circuit boards, wiring and cable bundles, power supplies, and enclosures. Additionally, it can be used to provide integrated EMI and RFI solutions for both military and commercial applications.

The effectiveness of 3M CN3490 2" X 4" 25 has been demonstrated in a variety of tests, including Excellent (Class A) emissions performance ratings for both commercial and military standards. In addition, it has been tested to ensure that it meets the most stringent requirements for shielding effectiveness, durability, and fire resistance. This makes it an ideal solution for those looking for reliable shielding materials for a variety of applications.

The use of 3M CN3490 2" X 4" 25 in shielding and absorbing materials applications can help to prevent a wide range of RFI and EMI interference. It is a durable and reliable material that is designed to provide effective and consistent protection, making it an excellent choice for those in need of shielding solutions.
