Radio Frequency Interference (RFI) and Electromagnetic Interference (EMI) can be prevented or at least reduced by shielding and absorbing materials. 3M AB5010 4.13" X 7.25"-25 is one such product from 3M that can be used in applications such as shielding electrical/electronic devices from EMI/RFI emission and absorption. It is also often used in printed circuits board (PCB) protective shielding, for both RFI and EMI radiations.

The 3M AB5010 4.13" X 7.25"-25 shielding materials are made of either tin-plated steel or aluminum, both providing a 99.9% shielding effectiveness against EMI/RFI radiations. These materials are already pre-scored for easy peeling and assembly. They are designed to protect sensitive electronic components and circuits from both EMI and RFI interference. They provide a full 360-degree circumferential coverage when applied, ensuring effective shielding performance. The materials come in different sizes such as 4.13" X 7.25"-25, 5.3" X 6.4"-36, and 42" X 72"-20, among others.

The working principle of these materials is based on absorption of EMI, RFI, and EMP radiations using a combination of various absorbers. An EMI absorber, for instance, has a wide frequency range to absorb both low and high frequency of EMI/RFI radiation. It is usually made of a highly conductive material, such as Ferrites, Nickel-Cadmium, Nickel-zinc, Aluminum-nickel-cobalt or Carbon-Barium-zinc, all of which have a 90% to 99% absorption rate. The absorbent material works by absorbing and dissipating the energy of the EMI/RFI radiations away from the sensitive electronic components.

Apart from absorbing the energy of the radiations, the 3M AB5010 4.13" X 7.25"-25 also blocks them from further penetrating the protected device. This is done by creating an electromagnetic field, which acts as an impenetrable barrier and prevents any further EMI/RFI radiations from entering the sensitive components. This field is usually created by placing the absorbers in in a grid-like pattern in order to provide nearly 100% coverage.

The 3M AB5010 4.13" X 7.25"-25 is used in many applications that require protection from EMI/RFI radiations. This includes telecommunication, power systems, automotive systems, and military systems. It can also be used to protect medical equipment, consumer and industrial electronics, computer systems, and surveillance systems. In addition to shielding and absorbing EMI/RFI emissions, the 3M AB5010 4.13" X 7.25"-25 can also be used for other purposes such as microwave heating and power transfer.

In conclusion, the 3M AB5010 4.13" X 7.25"-25 is an effective EMI/RFI shielding and absorbing material that prevents or at least reduces RFI and EMI emissions. It works by both blocking the EMI/RFI radiations from entering the device and absorbing them using an appropriate absorber. This material is suitable for a wide range of applications, including telecommunication, power systems, automotive systems, and military systems.
