Shielding and absorbing are two important considerations when it comes to ensuring Electromagnetic Interference (EMI) and Radio Frequency Interference (RFI) are avoided in electronics. Most electronic devices will generate electromagnetic radiation, and if these signals are not contained, they could interfere with other parts of the system, or surrounding systems. Since 3M AB5020HF 0.875”Circle-100 is designed for shielding and absorption of electromagnetic fields, it is classified as an RFI and EMI Shielding and Absorbing Material.

The 3M AB5020HF 0.875”Circle-100 is a shielded material specifically designed to absorb EMI/RFI signals from devices such as computers, monitors, and flat-panel displays. The material consists of two layers; a center layer of shielding and an outer layer of absorbing material. The shielding blocks the signal while the absorbing material captures any remaining signals, preventing them from escaping into the environment.

Shielding and absorbing are complementary techniques used to protect electronics from electromagnetic interference. The 3M AB5020HF 0.875”Circle-100 uses a combination of both techniques to provide the greatest security. The center layer of the material is composed of a Nickel/Copper/Nickel metal shield, providing a highly conductive surface that creates a Faraday cage around the device, which prevents radio frequency signals from entering or leaving. The outer layer of the material consists of an electrically conductive, light-absorbing foam, which absorbs any remaining electromagnetic fields. This combination allows the AB5020HF 0.875”Circle-100 to effectively absorb and block both high and low-frequency signals.

The 3M AB5020HF 0.875”Circle-100 is designed for use in a variety of applications. It is often used in medical electronics, industrial machinery, and computer systems to provide protection from EMI/RFI signals. It can also be used in appliances, consumer electronics, and automotive applications, to ensure operation of the device is not disrupted by electromagnetic interference.

The 3M AB5020HF 0.875”Circle-100 is an effective solution for ensuring EMI/RFI signals are blocked and absorbed, thereby protecting against interference with other devices. The two-layer design, consisting of a shielding layer and an absorbing layer, provides greater protection than a single-layer solution and is suitable for a variety of applications.
