The 3M™ Round Conductor Flat, Controlled Impedance Cable, 7700 Series, offers a unique construction with a metallic appearance but non-conductive surface. It features a thin conductive layer at each edge, encased in a translucent polyester outer layer over an aluminum foil layer. This cable is ideal for applications demanding controlled impedance and signal integrity, such as data transmission and signal routing in electronic devices. Users should evaluate its use in their application and may need to apply insulating tape to cover the aluminum layer as deemed appropriate.
