The through-hole, shrouded design with a locking ramp gives positive retention in high-vibration environments — the latch audibly clicks when fully mated, so a field technician knows the connection is secure. The 8 A per circuit rating is the headline current for power duty — this is a power header, not a signal-only part, and the tin-plated contacts (60.0 µin on the mating surface) are rated for the full 8 A at the stated operating temperature range of -40 °C to 105 °C. The 3.00 mm pitch and 0.118\" row spacing define the PCB footprint: a dual-row layout with 3.00 mm between centres in each row and between rows, which is standard for the Micro-Fit 3.0 family. The 0.125\" solder-post length suits a typical 1.6 mm PCB thickness; the 0.390\" insulation height above the board gives clearance for the mating receptacle's latch.","metaTitle":"Molex Micro-Fit 3.0 430451227, 12-Pos 3mm Header, 8A","metaDescription":"Molex 430451227 Micro-Fit 3.0 header, 12 positions, 3.00mm pitch, 8A per circuit, 600V, through-hole, tin-plated, shrouded, locking ramp.
