RFI and EMI Shielding and Absorbing Materials, such as the 3M AB5030HF 0.75" Circle-50/PK, provide protection against both electromagnetic interference (EMI) and radio frequency interference (RFI). Using shielding materials can block the transmission and reception of interference. Absorbing materials, on the other hand, are designed to limit the reflection of the interference signals. The combination of these two materials provides the strongest protection.The 3M AB5030HF 0.75" Circle-50/PK is a high frequency absorbing material designed to screen out electromagnetic noise in the range of 100kHz up to 1.7GHz in a wide variety of applications, including cabinets, housings, and door panels. It is a single-side solution material with a thickness of 0.7 mm and a skin depth of approximately 0.1mm. This material is designed to be easy to use with fastener holes around the edge to allow it to be attached to the surface. The material\'s construction provides effective protection against RFI and EMI, while having a low capacitance of 0.01pF/mm, ensuring minimum signal disruption.The 3M AB5030HF 0.75" Circle-50/PK uses a combination of metal and non-metal absorbent fibers that provide excellent shielding and absorbing performance. The non-metal fibers act as absorbers of the electromagnetic energy and have a low dielectric constant and loss tangent, which allows for a high absorption coefficient. The metal fibers provide shielding, blocking the transmission of signals. The combination of these two materials enables the 3M AB5030HF 0.75" Circle-50/PK to effectively block and absorb RFI and EMI interference.The 3M AB5030HF 0.75" Circle-50/PK has been tested and found to provide excellent EMI and RFI shielding and absorbing performance in various applications. In the automotive industry, the 3M AB5030HF 0.75" Circle-50/PK has been tested to provide up to 40dB of RFI and EMI shielding at frequencies of 40MHz to 1GHz. It has also been tested to provide up to 90dB of RF shielding at frequencies of 1GHz to 1.7GHz. The material is UL94V-0 approved, which means it meets the fire safety requirements.The 3M AB5030HF 0.75" Circle-50/PK is a highly effective EMI and RFI shielding and absorbing material, designed for applications requiring low signal disruption and high levels of protection against electromagnetic interference. This material is ideal for applications in the automotive and commercial industries, where shielding and absorbing performance is required for high frequency signals.
