Power Header for High-Current Board-Mount Applications
The Molex 1720420306 is the 3-position member of the Super Sabre 172042 series — a single-row, male-blade power header on a 7.50 mm pitch, rated 30 A per circuit at 600 V. This is a board-side power interconnect suited for server PSUs, industrial drives, battery packs, and any assembly where a 30 A per-circuit bus needs a solder-to-board connection.
The 100.0 µin silver plating handles the thermal and oxidation demands of repeated high-current mating; silver is the standard choice for power contacts at this current level, though it tarnishes faster than gold in corrosive atmospheres. The board lock (two integrated retention pegs) anchors the header during solder reflow and resists the pull force from a mated 30 A cable assembly.
