The 1761681-5 is a 50-position, vertical, low-profile IDC (Insulation-Displacement Connector) header assembly. It is designed with a standard 2.54 mm pitch and features a high-temperature PCT housing that is UL94V-0 rated and black in color. The phosphor bronze posts ensure reliable electrical performance, with gold plating on the mating area, tin plating on the solder end, and a nickel underplate over the entire post. This through-hole header is ideal for creating high-density, reliable connections in space-constrained applications such as industrial controls, telecommunications equipment, and consumer electronics.
