The Molex 430451223 is the 12-circuit, dual-row member of the Micro-Fit 3.0 43045 series — a right-angle through-hole header built for board-to-wire power and signal interconnects. 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.
