RFI and EMI shielding and absorbing materials are essential components used in the 78131073 application field. These shielding and absorbing materials are necessary for preventing electromagnetic interference (EMI) and radio-frequency interference (RFI) from disrupting or damaging electronic equipment. RFI and EMI shielding and absorbing materials are designed to attenuate, absorb, or redirect electromagnetic waves away from an electronic device, reducing the effect of EMI and RFI on the device. They are available in several forms and can be used in various applications, including home and indoor use, automotive, aircraft, office and industrial, and telecommunications.

One of the most common types of shielding and absorbing materials used in the 78131073 application field are metallic materials, such as aluminum, copper, and steel. These materials are chosen because they are effective in blocking and deflecting both EMI and RFI waves. Aluminum is anodized, painted, or electroplated for additional protection against corrosion and oxidation. Copper is often used in combination with nickel to achieve the highest levels of shielding effectiveness. All these metals can typically be combined into perforated sheets or meshes and are often used to encase electronic components or systems.

In addition to metallic shielding and absorbing materials, other types of shielding and absorbing materials are also available, such as non-metallic materials such as fabric and plastics, and composites containing both metallic and non-metallic materials. Non-metallic materials, such as fabrics, usually consist of fibers that are woven together to form a tight mesh with small gaps. This material is lightweight and can be used in areas that may be difficult to access. Non-metallic materials are typically used in applications that require an added layer of protection, such as those near radio or TV transmitters.

Composite RFI and EMI shielding and absorbing materials are typically used in applications where higher levels of shielding are required. These composite materials are usually made from layers of metal foil, a conductive polymer, and other materials, such as ceramic fibers or glass fibers. The layers are combined in such a way that each layer provides an added level of protection, increasing the overall shielding effectiveness. As a result, composite materials are often used in military and aerospace applications.

In short, RFI and EMI shielding and absorbing materials are essential components used in the 78131073 application fields. Various types of materials, including metallic, non-metallic, and composite materials, are used for attenuating, absorb, or redirecting EMI and RFI waves away from electronic devices. The choice of material depends on the application and the level of shielding required, and all of these materials play a vital role in reducing the effects of EMI and RFI on electronic equipment.
