5-CN3490-1/2-3R

RFI and EMI shielding and absorb materials have been used to protect electronic devices from radiation frequencies that can damage and/or disrupt the operation of the device. 5-CN3490-1/2-3R is an example of such a shield that is often used in the field of digital electronics. Its shielding application and working principles are outlined in this article.

5-CN3490-1/2-3R is a nickel alloy foil that consists of a thin, single layer of pure nickel laminated to a thick polyester film. This shielding material provides effective protection from both high frequency electrical fields (HF radio frequencies) and electromagnetic interference (EMI). The nickel layer helps to absorb high frequency radiation, while the polyester provides a barrier against EMI. This combination of materials makes 5-CN3490-1/2-3R a highly effective and reliable shielding material.

The 5 CN3490-1/2-3R shielding application is most commonly used in digital electronics to reduce conducted EMI. This shielding material is applied to the exterior surface of the product. The nickel layer absorbs and dissipates any high frequency radiation that it encounters, while the polyester film serves to block EMI. It is also used as a printed circuit board shield, where it is used to line the internal pathways to reduce interference. Additionally, it is used to provide protection against environmental radio frequency interference (RFI), and to reduce the risk of electrostatic discharge (ESD) to sensitive electronic components.

In terms of working principles, the 5-CN3490-1/2-3R shielding material works on the principle of electromagnetic shielding. This shielding material works by absorbing and dissipating high frequency electrical fields (HF radio frequencies) and electromagnetic interference (EMI) into the surrounding environment. The nickel layer absorbs and dissipates the radiation, while the thick polyester film provides a barrier to prevent EMI from reaching the product\'s electronics.

In terms of durability, the 5-CN3490-1/2-3R shielding material is highly reliable and is designed to withstand exposure to harsh environmental conditions. Its shielding capability does not reduce even after long periods of use. The nickel layer has excellent corrosion resistance, and the polyester film is resistant to aging and is able to maintain a consistent level of shielding performance.

Overall, the 5-CN3490-1/2-3R shielding material is an effective and reliable solution for shielding digital electronics from high frequency electrical fields and electromagnetic interference. It is easy to apply, and its durable construction ensures that it will provide consistent shielding performance for a long time. It is an ideal solution for products that need protection from environmental radio frequency interference and electrostatic discharge.
