RFI and EMI are terms used to describe the interference electromagnetic radiation can have when it is emitted into any electrical circuit, causing it to malfunction or distort signals. Shielding and absorbing materials, such as 3M CN4190 3/4" X 2"-100, are used to protect circuits against such interference.

3M CN4190 is a thin, flexible copper-clad laminate sheet that provides superior EMI and RFI shielding. It is designed to provide an effective barrier between electronic circuits and sources of electromagnetic interference. The laminate consists of 0.0017" of copper foil bonded to a 0.0019" thick polyimide dielectric film. It is rated for operation at temperatures up to 350 °F and its flexible nature makes it an ideal choice for applications where flexibility is required.

The primary use of 3M CN4190 is in the field of electrostatic shielding. Electrostatic shielding is used to reduce radiated or conducted emissions by providing a physical barrier between the source and the receiving circuit. The board\'s copper-polyimide surface resists flexing, which helps to maintain a low-inductance shield. This helps to reduce the transmission of electromagnetic and radio frequency interference (EMI and RFI) which can cause interference to signals, and potentially disrupt or damage unprotected electronics.

3M CN4190 is also used to provide protection from static electricity. The copper foil surface is designed to ground effectively, reducing the risk of electrostatic discharge which can be damaging to electronic components. In addition to this, the laminate can be used to shield printed circuits from oxidation, which can improve the longevity of the components and increase reliability.

The 3M CN4190 is also highly used in RF applications as a shield as well as for decoupling. It can be used to isolate microstrip traces and reduce cross talk. The uniform thickness and flexibility makes it ideal for applications such as RF shields for enclosures, medical device housings, and other electronic components.

In summary, 3M CN4190 3/4" X 2"-100 is used for various applications in RFI and EMI shielding and absorbing materials. It is designed to be a highly effective electrostatic shield for protecting circuits from electrostatic discharge, EMI, and RFI. It also has other applications such as decoupling, RF shielding, and reducing oxidation. By utilizing the copper-polyimide laminate, this material allows for a uniform and flexible shield, ideal for a variety of EMI/RFI shielding applications.
