It carries an 8 A per circuit rating at 600 V, making it a capable choice for distributing power on a PCB rather than just passing signal-level current. The 3.00 mm pitch and 0.118\" row spacing give enough creepage for that voltage rating without forcing an oversized board footprint — a practical balance for a 4-position part. Each contact is sized to carry bus-level current on a power rail or motor drive line. That's a heavy tin deposit — thicker than the typical 40–80 µin found on commodity headers — which gives better wear resistance for repeated mating cycles in field-serviceable equipment. For a 4-position power header on a 48 V or 400 V bus, this gives substantial headroom. The male pins are square brass alloy, tin-plated, and the solder tails are 0.125\" (3.18 mm) long — a standard through-hole length that fits most 1.6 mm PCBs. Termination is solder-only — no press-fit option on this variant. The board lock holds the header in position during the wave or selective solder process, preventing skew from the solder pot's wave turbulence. After soldering, the board lock is buried in the plated through-hole and adds mechanical shear resistance to the joint.","metaTitle":"Molex Micro-Fit 3.0 430450400 Header, 4 Pos R/A, 8A","metaDescription":"Molex 430450400 Micro-Fit 3.0 header, 4 circuits dual-row, 3.00mm pitch, 8A/600V, right-angle THT, tin plating, board lock, active production.
