770829-1 is a PC Board surface mount right-angle pin header designed for 4-circuit in-line connector configurations in the Commercial MATE-N-LOK connector family. The housing is constructed from nylon with black color and features a UL94V-2 flammability rating, with phosphor bronze pre-tin contacts. The header has a solder tail width of 0.052 inches (1.32 mm) and is designed for use with standard 0.062-inch (1.57 mm) thick PC boards. This component mates with socket housings and insulation displacement connectors (IDC), making it suitable for applications in the disk drive industry and other commercial electronics requiring reliable wire-to-board connections. The compact design and surface mount compatibility enable efficient PCB assembly and integration into space-constrained applications.
