The 3.00 mm pitch provides enough creepage for the 600 V rating without forcing an oversized board footprint, while the gold-plated mating contacts (30.0 µin) handle repeated mating cycles without corrosion. Tin-plated solder tails (100.0 µin) wet well with standard lead-free profiles, so no special paste or preheat is needed. Rated 8 A per circuit at 600 V, the limiting factor here is the contact temperature rise, not the contact itself — the LCP housing (UL94 V-0) handles the heat, but derate above 105 °C operating ambient. The locking ramp clicks home and won't back out under vibration. Termination is solder-only — no press-fit option on this SMT variant.","metaTitle":"Molex Micro-Fit 3.0 430451208, 12-Pos Header, 8A, 600V","metaDescription":"Molex Micro-Fit 3.0 header 430451208, 12 circuits dual-row, 3mm pitch, SMT right-angle, gold contacts, 8A per circuit.
