Introduction to RFI and EMI - Shielding and Absorbing Materials

The term Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) signify interference generated due to the presence of electromagnetic radiation (EMR). RFI and EMI products are designed to restrict the passage of EMR, which causes disruption in the operation of components and systems. Shielding and Absorbing Materials (SAMs) for RFI and EMI are the premier choice for electromagnetic protection due to their robust nature and numerous features. This article will look at the 78153112 application field and working principle of Shielding and Absorbing Materials.

Types of Shielding and Absorbing Materials

The variety of Shielding and Absorbing Materials used in RFI and EMI shielding include conductive films, foils, fabrics, gaskets, screen meshes, conductive paints or coatings, and more. Each of these materials have their unique advantages and features, and they can be used in combination for increased effectiveness. Conductive films are thin films made from a variety of metals, such as aluminum, copper, nickel, tin or zinc. These films adhere to surfaces and provide high EMI shielding performance. Conductive foils are similar to films, except they are thinner and more lightweight and offer lower shielding performance. Metallic meshes and screens are also available, and they are typically made from woven or knitted metal fibres. Conductive fabrics consist of interwoven metal fibres and provide an excellent combination of shielding effectiveness and flexibility. Gaskets made from rubber or silicone are also popular, and they offer superior EMI shielding for hermetically sealed openings. Conductive paints and coatings are available for added protection, and they provide excellent coverage of large areas while concealing the shielding material.

78153112 Application Field and Working Principle

78153112 is a special type of Shielding and Absorbing Material used in RFI and EMI protection. It is made from premium quality aluminum and contains a layer of conductive rubber on the surface. This material provides an effective EMI shielding performance of up to 100 dB in the frequency range of 10 MHz to 30 GHz. The primary purpose of 78153112 is to prevent any radiation emitted from the protected equipment or device from interfering with other systems or components. The working principle of 78153112 is that it creates a barrier between the protected equipment or component and the ambient environment. This barrier is created by the combination of the conductive aluminum layer and the conductive rubber layer. The conductive rubber layer absorbs any incoming electromagnetic radiation, while the aluminum layer absorbs any radiation that has passed through the rubber layer. The combination of these two layers provides a high level of protection from EMR interference.
