RF and EMI shielding and absorbing materials are used to provide levels of protection from various forms of radiation. These materials are used in many applications such as aircraft, military and medical equipment, communications systems and consumer electronics. The use of shielding and absorbing materials is critical to the successful operation of these devices as they reduce the level of radiation that can penetrate into the device. In this article, the application field and working principle of 21109145 shielding and absorbing materials are discussed.

21109145 shielding and absorbing materials are designed for use in radio frequency and electromagnetic interference, or RFI/EMI, applications. These materials are often used to protect electronic devices from the damaging effects of intense electrical and magnetic fields. They are also used to block unwanted radio signals from entering into and interfering with the performance of the device. 21109145 shielding and absorbing materials are effective in blocking out RFI/EMI signals in the frequency range 10 kHz up to 8 GHz.

21109145 shielding and absorbing materials are made from a variety of materials, including metal, plastic, rubber and composite materials. All materials must meet specific requirements for shielding effectiveness. Metals, such as aluminum, are typically used to provide the highest levels of electrical conductivity, while plastics, rubbers and composite materials are used to provide lower levels of electrical conductivity. These materials can also be combined to create hybrid materials that provide higher levels of shielding effectiveness.

The shielding effectiveness of 21109145 shielding and absorbing materials is determined by their attenuation efficiency. Attenuation is a measure of how well a material can absorb, reflect and/or scatter radio frequency and electromagnetic radiation. This attenuation efficiency can vary based on the material composition, thickness and density of the material. The higher the attenuation efficiency, the more effective the material is at reducing the level of electrical and magnetic fields passing through it.

21109145 shielding and absorbing materials can also be used to prevent interference between two or more electronic devices. This is done by providing a barrier between the devices that will effectively block out any unwanted radio signals. This is particularly useful in applications such as aircraft, where the use of shielding materials can reduce interference between sensitive cockpit equipment and other electronics such as communication radios.

21109145 shielding and absorbing materials are also commonly used in medical devices. These materials can be used to reduce the levels of electrical and magnetic fields generated by the device. This is especially important for devices such as pacemakers and other implantable devices, as these can be vulnerable to interference from external signals. By using shielding and absorbing materials, the chances of interference and other damages are greatly reduced.

In summary, 21109145 shielding and absorbing materials are important tools for protecting electronic devices from RFI/EMI signals. These materials provide an effective barrier against unwanted signals, while also reducing the levels of electromagnetic and radio frequency radiation that can penetrate into the device. They are widely used in a range of applications like aircraft, military and medical equipment, communications systems and consumer electronics.
