Its 3.00 mm pitch and 600 V rating give enough creepage for industrial and telecom power distribution without forcing an oversized board footprint. The 8 A per circuit rating is a solid middle ground for moderate-current harnesses, and the 30.0 µin gold plating on the mating surface handles repeated connect/disconnect cycles in field-service equipment or corrosive environments. Active lifecycle, ROHS3 compliant — no last-time-buy pressure.","metaTitle":"Molex 430451223 Micro-Fit 3.0 Header, 12 Pos, 3mm, R/A","metaDescription":"Molex 430451223 Micro-Fit 3.0 header, 12 positions (2×6), 3.00 mm pitch, right-angle through-hole, 8 A, 600 V, gold-plated contacts, shrouded, board lock, UL94 V-0.
