It's designed for board-to-wire power interconnects, typically used in automotive, industrial, medical, and telecom harness assemblies where a reliable, lockable connection is needed. The 8 A per-circuit current rating is the headline number, but the contact plating grade is what governs the real duty. The mating side carries 15.0 µin of gold — a standard thickness for moderate mating-cycle life and corrosion resistance in environments that aren't clean-room dry. The solder tails are tin-plated, which is fine for the SMT reflow process. ## Mating half and sourcing reality This header mates with the standard Micro-Fit 3.0 receptacle housing (the 43025 series) loaded with the 43030 crimp terminals. On the sourcing side, the part is active and ROHS3 compliant, so there's no last-time-buy pressure. The 12-position 430451216 sits alongside the 10-position 430451210 in the same Micro-Fit 3.0 SMT header family. Both share the 3.00 mm pitch, 8 A rating, gold mating contacts, board lock, and locking ramp. The difference is purely the position count — 12 circuits vs 10 circuits — so the choice comes down to matching your BOM's circuit count. The 12-position version is 3.00 mm longer in the body to accommodate the extra two pins, but the footprint pitch and row spacing are identical, so the pad layout scales linearly.","metaTitle":"Molex Micro-Fit 3.0 430451216, 12-Pos SMT Header, 3mm Pitch","metaDescription":"Molex 430451216 Micro-Fit 3.0 SMT header, 12 positions, 3.00mm pitch, 8A, gold contacts, board lock, UL94 V-0.
