RFI and EMI – Shielding and Absorbing Materials

RFI and EMI shielding is one of the most important components of electronic design. Without proper shielding, noise can interfere with radio frequency and electromagnetic interference, which can degrade performance. Shielding materials act as barriers to contain and reduce the levels of radio frequency and electromagnetic interference that can affect the performance of electronic components.

3M CN3490 2" X 1.25"-100 is a specialized shielding material with unique characteristics designed to meet the exacting demands of particular applications. It is suitable for use in areas where shielding effectiveness is critical, such as in military, aerospace, and in various industrial areas.

Application Field

3M CN3490 2" X 1.25"-100 is designed to provide an effective barrier against both magnetic fields and radio frequency interference. This material has a low-profile configuration, making it ideal for restricted spaces or when size constraints make the use of traditional shielding materials impractical.

This material is typically used in areas such as: military equipment, aircraft, satellite communications, automotive and industrial applications, and even consumer electronics. This shielding material can also be used to prevent electronic interference from seeping into or out of programs containing sensitive data in various government and private sectors.

Working Principle

3M CN3490 2" X 1.25"-100 works by creating a conductive barrier between the source of the noise and the components being protected. This material is usually constructed from an alloy of steel, copper, aluminum, tin, and other metals. This alloy is then bonded to a non-conductive backing in order to create a shield which reduces the amount of energy that can pass through it.

The material is designed to absorb RF and EMI radiation. This is done by absorbing the energy of the incoming radiation and dissipating it in a harmless electromagnetic field. The advantage of this absorption method is that it does not require as much energy as a traditional Faraday cage or other shielding material.

Finally, 3M CN3490 2" X 1.25"-100 also reduces the effect of corona in cables. Corona is an effect between two conductors that can cause unwanted electrical noise and is most often seen in longer cables. By coating the conductors in 3M CN3490, the electrical noise is reduced and the cable is better able to handle the higher current levels associated with long cables.

Conclusion

3M CN3490 2" X 1.25"-100 is a specialized shielding material designed for use in sensitive applications where effective shielding is essential. It is effective in both RF and EMI applications as well as in areas where corona is an issue. By absorbing the energy of the incoming radiation and dissipating it in a harmless electromagnetic field, 3M CN3490 provides effective protection for sensitive electronic components.
