The 5-CN3490-2 is a type of shield material that can provide shielding or absorption of electromagnetic interference (EMI) and radio frequency interference (RFI). Shield material, also known as EMI/RFI shielding, is used to provide protection from electromagnetic radiation. In most cases, this type of shielding is used in order to minimize the levels of noise generated by the interference. This type of material is often found in electrical and electronic applications where the interference is high, such as in communications systems and household appliances.
The 5-CN3490-2 is a type of shielding material made of silver-plated copper foil laminated to a polyethylene-terephthalate (PET) film. It is designed to block signals in the frequency range of 30 MHz to 3 GHz. This type of material is suitable for indoor applications such as enclosures, data cabinets, and EMI/RFI barriers. The frequency-dependent absorbing properties of the material enable it to absorb signals in the frequency ranges below 30 MHz.
The material is also highly conductive, making it an ideal material for shielding and absorbing EMI/RFI. The PET film coating helps reduce losses due to reflection or refraction of signals. The material is also flexible and easy to work with, which makes it ideal for applications that require intricate shapes and sizes for shielding.
In terms of working principle, the 5-CN3490-2 is designed to block or absorb signals, depending on their frequency. The material is designed to absorb signals in the frequency ranges below 30MHz, while blocking signals in the 30MHz to 3GHz frequency range. The shielding material\'s frequency-dependent absorption properties help to reduce the level of interference by preventing the transmission of signals beyond the specified frequency range.
The 5-CN3490-2 is primarily used in a number of different applications. Most commonly, this type of material is used for EMI/RFI shielding in communications systems, household appliances, and electronic and electrical components. It is also used in electronics where interference from other signals is a significant problem. The material can also be used to provide radio wave barriers for portable electronic devices such as mobile phones and laptops. These shields can be used to reduce the level of interference present in the surrounding environment.
Aside from shielding and absorbing interference, the 5-CN3490-2 can also be used for grounding purposes. Since the material is highly conductive, it can be used to provide a common point where all electrical components can be connected, as well as for providing a low impedance path for current. The material is also non-toxic and complies with European RoHS directives, making it an ideal material for applications in industries that require maximum safety.
In conclusion, the 5-CN3490-2 is a type of flexible EMI/RFI shielding and absorbing material that is highly conductive and easy to work with. It offers excellent protection from interference by blocking or absorbing signals depending on their frequency. This type of material can be used for a variety of applications ranging from shielding communications systems and household appliances to providing radio wave barriers for portable electronic devices. Additionally, the material can also be used for grounding purposes due to its high conductivity and compliance with RoHS directives.
