3M CN3490 2" X 5"-25

The 3M CN3490 2" X 5"-25 is a shielding and absorbing material used in the field of RF and EMI protection applications. As one of 3M\'s EMI shielding and absorbing materials, the CN3490 contains both a conductive and a dielectric layer to provide effective high frequency shielding and absorbing in a wide frequency range. The two-part matrix of conductive and dielectric layers provides a combination of properties to reduce the transmission of unwanted signals.

The CN3490 is designed for use in diverse RF and EMI protection applications. Its features include light weight, low-profile, high flexibility and low cost, which make it ideal for applications such as waveguides, antennae, and RF enclosure materials. Its great flexibility and low thickness make it ideal for use in space constrained applications.

In terms of working principles, the CN3490 EMI shielding and absorbing material works by providing a physical barrier between RF fields and the sensitive equipment. The conductive mesh layer creates a Faraday cage to form a physical barrier against RF signals and EMI interference. The dielectric layer of the CN3490 acts as a buffer to absorb and dissipate unwanted RF signals. The combination of these two layers helps to provide an effective floor level of radio frequency and electromagnetic interference protection.

The CN3490 is also designed to reduce the amount of RF that penetrates a shielded area, making it an ideal solution for military, aerospace, and medical applications. With its ability to provide effective protection in a wide range of frequencies, the CN3490 is also widely used in consumer electronics, computer systems, and telecommunications.

The CN3490 is easy to install and configure, and can be used in a variety of ways. It can be used in combination with other shielding systems such as metal sheets or conductive mesh to further enhance RF shielding effectiveness. It can also be used alone for easy and cost-effective RF and EMI protection.

The CN3490 is a robust and reliable option for a variety of RF and EMI protection applications. Its versatile design, combined with its affordability, make it an attractive choice for cost conscious users. The CN3490 is available in various sizes and shapes to meet any application requirement.
