RF and EMI shielding materials are available in a variety of shapes and sizes, including 3M CN3190 2" X 3" - 25. The main purpose of these materials is to protect electronic devices from interference from external sources, such as electromagnetic radiation, electrostatic fields, and radio frequency interference (RFI). They are also used in applications such as high power equipment and low power circuitry, as well as in the automotive and aerospace industries.

3M CN3190 is composed of a combination of conductive and non-conductive materials. The conductive material is used to provide an electrostatic shield, blocking RF and EM wave interference from entering or leaving. Non-conductive materials are used to support and stabilize the conductive material, and to reduce the likelihood of electrical shorts. Together, these materials form a barrier which provides effective RF and EM shielding.

The 3M CN3190 material is typically applied as a layer over the electronic device and its components, or under and around. It is then covered with a protective material such as vinyl or plastic. This layer shields the device from external interference and absorption of radiation and heat. It also provides protection against shock and vibration.

To ensure maximum effectiveness, 3M CN3190 should be applied to any area that is subject to radiation, RF signals, or where static fields are generated. This includes areas around power circuits and transformers, antenna bases, and other locations where interference is present.

3M CN3190 is highly flexible and can be applied to achieve various levels of RF and EM shielding. The material is also resistant to most types of abrasion and corrosion. In addition, the material is non-toxic and does not absorb harmful chemicals.

The working principle of 3M CN3190 is based on the principle of Faraday’s cage, which states that a metal enclosure will block out the effects of electromagnetic fields. This is achieved by creating a continuous conductive path around the device or component, which will reflect or absorb any incoming EM fields. This reflects or absorbs many types of noise, radiation, and other interference, and helps to keep the device or component in an electromagnetic quiet zone.

3M CN3190 is an effective shielding material for many electronics applications. It is easy to install, provides reliable protection from interference, and is radiation and heat resistant. Its wide range of uses make it a popular choice for use in a variety of electronics and industrial applications.
