RFI and EMI-shielding and absorbing materials are essential for most applications where electromagnetic interference (EMI) or radio frequency interference (RFI) needs to be blocked or reduced. 3M is a world leader in shielding and absorbing materials like their 1267 Circle-0.5"-250. This product is specifically designed for EMI/RFI shielding applications and can be used in a variety of products from telecom and datacom applications to medical equipment and consumer electronics.

The Circle-0.5"-250 has a split design that consists of two concentric circles with 0.25" gap. This space is filled with conductive absorbent material known as EMI absorber, which provides effective absorption of EMI/RFI over a wide frequency range. The circles can be reinforced with adhesive tape for attaching the material and keeping it in place.

The Circle-0.5"-250 works by absorbing electromagnetic energy. When an EM wave strikes the material, it is dissipated into heat. The material has an impedance that is finely tuned to match the frequency of the EM wave, which allows the energy to be converted into heat quickly. This process allows the material to keep EMI/RFI away from sensitive components and electronics, protecting them from damage.

The Circle-0.5"-250 has many uses, but is especially useful in telecom and datacom applications. It can be used to shield and absorb cables, connectors, and equipment from EMI/RFI, preventing interference from corrupting or disrupting signals. It can also be used as a test device for certifying conformance to EMI/RFI standards. It is also suitable for protecting devices from reverse leakage and other forms of interference.

Overall, the 3M 1267 Circle-0.5"-250 is an effective and reliable solution for shielding and absorbing EMI/RFI. It is suitable for a variety of applications, from telecom and datacom to medical equipment and consumer electronics. The product utilizes advanced technology and is easy to install, making it a great choice for a variety of needs.
