The 3M AB5020 CIRCLE-0.5"-250 is a protective device designed to help reduce or eliminate electromagnetic interference (EMI) and radio frequency interference (RFI). It provides effective shielding to protect electronics from unwanted noise and interference. It also reduces or eliminates the radiated emissions from electronic equipment, which can interfere with other equipment, reduce the effectiveness of communications systems and even disrupt communication networks.

Most RFI and EMI can be effectively blocked and absorbed by the use of appropriate shielding materials. The AB5020 shielding material is designed to provide shielding effectiveness of up to 125 dB and a working frequency range of 20 MHz to 18 GHz. This shielding material is applied to a polyester film backing which provides the mechanical strength and the shielding effectiveness.

The AB5020 shielding material is laminated to the backing material with an electrically conductive polymer adhesive which achieves the performance of a copper foil shielding material. It offers low transmissive loss properties which makes it suitable for use in many applications. It is also easily cut and formed to the desired shape for custom shielding applications.

The 3M AB5020 CIRCLE-0.5"-250 shielding material is ideal for use in a variety of applications including shielding of electronic devices such as radios, cell phones, radar systems, and medical imaging. It can also be used to shield cables, as well as shielding in electronic enclosures. It is widely used in the aerospace, telecommunications, military, and industrial sectors.

The working principle of the 3M AB5020 shielding material is that it reflects and absorbs incoming RFI and EMI, thus preventing it from entering the enclosed area. The shielding material provides an electrically conductive surface which helps to absorb and attenuate the transmitted energy. It also provides a reflective surface that will however open-circuits any signal trying to travel through it.

The AB5020 shielding material is designed to be easy to install with a peel and stick application. It can be easily bonded to existing or custom designed metallic enclosures for maximum shielding performance. The adhesive also provides a smooth and clean surface finish, which ensures maximum shielding effectiveness.

The 3M AB5020 CIRCLE-0.5"-250 is an effective and versatile shielding material for use in a variety of applications. It provides excellent shielding performance and is highly durable. It is also easy to install, provides a smooth finish, and is backed by 3M’s technical support. It is an ideal choice for protecting electronic devices from RFI and EMI.
