The Molex 430451015 is a 10-circuit, dual-row SMT header from the Micro-Fit 3.0 43045 series, designed for board-to-cable/wire power interconnects. The tin-plated mating surface handles the current but limits the mating cycle count — this is a set-and-forget connector for production harnesses, not a daily-disconnect test point. The board lock feature holds the header down during reflow so the SMT pads don't lift under the shear from the cable strain.
The 600 V rating is paired with a 3.00 mm pitch and a 0.390" insulation height — the LCP housing (UL94 V-0) provides the creepage path. Surface-mount termination with board lock means the header is reflow-soldered and the plastic pegs anchor into plated through-holes.
