Shielding materials are used to protect electronic equipment from the adverse effects of electromagnetic interference (EMI) and radio frequency interference (RFI). In order to achieve this protection, shielding materials need to act as barriers to prevent the emission of EMI and RFI from the source, and also to absorb or ‘shunt’ away radiation that may be present in the surrounding environment. In some cases, additional components such as absorbers and/or filters may be required to complete the shielding package.

3M AB5050 0.5"SQ-250 is a shielding and absorbing material developed by 3M Corporation. It is a multi-layer composite film that consists of an amorphous polyester (Mylar) base film. It has been designed to provide up to 90 dB shielding from EMI at frequencies ranging from 10 kHz up to 5.3 GHz. The AB5050 0.5"SQ-250 is especially effective at providing EMI and RFI shielding in applications such as electronic enclosures, and particularly in medical equipment, such as pacemakers, due to its durability and flexibility. It has a wide range of application areas, including high voltage power, telecommunications, automotive, and aerospace.

The primary function of the 3M AB5050 0.5"SQ-250 is to absorb EMI/RFI radiation and reduce the strength of the electric field. To absorb the radiation, the material includes a conductive filler which is designed to spread the current over its entire surface area. This ensures that a maximum amount of energy is absorbed, and reduces the risk of reflected energy causing interference. The Mylar base gives the material mechanical strength and electrical stability. A flexible adhesive layer is also applied to one side of the material, which allows it to be easily installed in most applications.

The 3M AB5050 0.5"SQ-250 is a versatile shielding and absorbing material that can be used in many different types of applications. It is designed to provide excellent protection from EMI and RFI, and is able to absorb as well as block radiation. It is highly durable and flexible, making it an ideal choice for medical applications, and provides excellent performance in a wide range of application areas. With its effective shielding capability and wide range of applications, the 3M AB5050 0.5"SQ-250 is an excellent choice for shielding and absorbance of EMI and RFI.
