RFI and EMI - Shielding and Absorbing Materials

Radio frequency interference (RFI) and electromagnetic interference (EMI) are two of the most common and well-known terms in the field of electronics and telecommunications. RFI is usually the result of radio waves emitted from one device, while EMI is caused by electromagnetic signals from other electronic devices. In order to prevent these signals from being picked up by nearby electronic devices, shielding and absorbing materials such as 3M 1181 CIRCLE-0.5"-250 are used as a means of protection.

3M 1181 CIRCLE-0.5"-250 is an electrically conductive adhesive tape designed to provide static shielding and EMI/RFI absorption. The tape is composed of a metalized polyester film backing and a conductive acrylic adhesive. It has a unique combination of properties that make it ideal for a wide range of EMI/RFI absorption applications. Its adhesive properties provide excellent adhesion to a variety of surfaces, while its low-noise properties make it ideal for absorbing EMI/RFI. This product is qualified to NASA-Low Outgassing specifications and it meets the requirements of UL 746C.
