49L-CBSA-1.75X3.25X0.4

RF shields - electromagnetic shielding materials designed to protect electronic equipment from electromagnetic interference (EMI) - are widely used in a variety of technological and industrial applications. 49L-CBSA-1.75X3.25X0.4 is an example of a type of RF shield that is designed specifically to provide EMI protection for enclosures and other components where space is limited. This type of RF shield is typically used in power supplies, computer peripherals, and consumer electronics.The fundamental purpose of an RF shield is to limit the amount of electromagnetic radiation that is able to travel from one point to another. In the case of the 49L-CBSA-1.75X3.25X0.4 RF shield, this is achieved by creating an enclosed cavity within which electromagnetic radiation is highly attenuated by the metal structure of the shield. The shield itself is made up of several layers of aluminium alloy, provide shielding efficiency of up to 95 dB.In terms of application, the 49L-CBSA-1.75X3.25X0.4 is designed to provide EMI protection for small, power-sensitive components, such as those used in personal computers, consumer electronics, and medical equipment. It is especially useful for reducing EMI radiation emissions in mobile device designs, where its low-profile design and high shielding efficiency makes it an ideal choice.The working principle underlying the 49L-CBSA-1.75X3.25X0.4 RF shield is based on the concept of faraday cages. The faraday cage is a metal enclosure that is constructed in such a way that it completely encloses any electromagnetic radiation, preventing it from escaping to the external environment. The 49L-CBSA-1.75X3.25X0.4 is designed to create such an enclosed space, in which electromagnetic fields are unable to penetrate. As the fields try to pass through the layers of aluminium alloy, they are blocked and weakened due to the skin effect, ensuring that the fields created within the enclosure are kept at a minimum.The 49L-CBSA-1.75X3.25X0.4 is also designed to allow the passage of thermal energy through its structure, while still providing high levels of EMI protection. This is achieved through the use of a thermally conductive shield substrate, which provides a path for thermal energy to dissipate while still providing the necessary levels of shielding.In summary, the 49L-CBSA-1.75X3.25X0.4 RF Shield is a low-profile shielding material designed to provide EMI protection for small components and devices. Its construction is based on the concept of faraday cages, and it is capable of reducing electromagnetic radiation emissions to a minimum. It is also designed to allow the passage of thermal energy through its shield substrate, making it an ideal choice for mobile device designs.
