The Molex 430451828 is the 18-circuit member of the Micro-Fit 3.0 43045 series — a dual-row 3.00mm-pitch male header rated 8A per contact at 600V. The mating interface carries 15.0 µin gold plating over brass; the solder post side steps down to 100.0 µin tin for wave or hand-solder board termination. Four-wall shrouding and a locking ramp hold the mating half under vibration — the board guide feature keeps the header aligned during through-hole assembly. The LCP housing is UL94 V-0 rated and specified from -40 to 105 °C, placing it squarely in automotive and industrial harness environments.
What the 8A and 600V ratings mean for your circuit
8A per contact is the per-circuit rating — not a derated aggregate. The 600V rating exceeds typical industrial automation rails, so circuit count and current per position drive the fit decision.
