RFI and EMI shielding and absorbing materials are essential components for a wide range of equipment and installations. 3M CN3190 5" X 54.5YD is one such material that is used for shielding and absorbing electromagnetic interference (EMI) and radio frequency interference (RFI) in electronic systems. This article outlines the application and working principle of 3M CN3190 5" X 54.5YD.

3M CN3190 is a nickel and copper, two-sided tape designed for electromagnetic interference shielding and radio frequency interference suppression in electronic components. The tape consists of a nickel-plated polyester film on one side, and a copper laminated on the other. It is available in five inch (5") widths and 54.5 yard (50M) lengths. The nickel-plated side provides effective EMI shielding while the copper provides lower losses, improved grounding, and better longevity.

The application of 3M CN3190 5" X 54.5YD requires bonding or layering onto components, cables, and enclosures. It is often applied when a grounded EMI shield is needed. The tape provides excellent adhesion to many surfaces and is shielded from the environment, making it ideal for installations that require robust shielding in highly variable climates. It offers effective EMI and RFI shielding when applied in electrical components such as circuit boards, cables, and connectors. This helps to reduce or eliminate the effects of EMI or RFI interference.

The working principle of 3M CN3190 5" X 54.5YD is the reflection, absorption, redirection, and transmission of EMI or RFI signals. The nickel-plated side of the tape provides effective shielding since nickel is a good conductor of electricity. This helps to reflect electromagnetic waves back to the source. The copper laminated on the other side offers improved grounding and helps to absorb EMI and RFI signals. This helps to prevent either signals from escaping and interfering with nearby signals or receiving interference from nearby signals.

In conclusion, 3M CN3190 5" X 54.5YD is an effective electromagnetic shielding and radio frequency interference reducing material. It is applied to electrical components with the aim of reducing or eliminating the effects of EMI or RFI interference. The tape provides a metallic layer which is capable of reflecting, absorbing, redirection, and transmission of EMI or RFI signals, thus providing effective shielding.
