The Amphenol RFs 50 Ω AMC cable assemblies are a state of the art component. They are perfect for space-constrained board-to-board connections in small devices. Their Snap-on interface performs superbly under shock and vibration conditions, making them ideal for wireless handheld devices. It is a definite must have for anyone who seeks quality and reliability in components they purchase. It also features a low profile (2.5 mm off the board) and offers an extremely small board footprint (3 mm x 3 mm). This series is compatible with the U.FL interface. This is truly a wonder of modern technology and ingenuity.
