It carries a 0.200" (5.08 mm) mating pitch, rated 15 A per circuit at 250 VAC, with tin-plated male pins on a copper alloy contact base. The header is surface-mount, right-angle, with a shrouded 4-wall housing that protects the pins during mating and handling.
Key features and deployment context
The 770829-1 includes a board guide and board lock — the guide aids alignment during pick-and-place, and the lock provides SMT reflow retention plus vibration resistance once soldered.
Termination is solder — the SMT right-angle tails reflow onto the board pads. The 4-wall shrouding prevents pin stubbing during blind mating and provides polarization.
Comparison with through-hole sibling 770846-1
The 770846-1 is the through-hole, right-angle version of this same 4-position, 0.200"-pitch header, sharing the 15 A rating, 250 VAC rating, tin-plated contacts, board lock, and UL94 V-2 housing. The only functional difference is the mounting method: the 770829-1 is SMT, while the 770846-1 is through-hole. Choose the SMT version for reflow assembly lines; choose the through-hole version for higher mechanical retention or wave-solder processes.
