It carries a 3.00 mm pitch and is rated 8 A per contact at 600 V — the 8 A per circuit is the series' standard power rating, sized for moderate-current DC rails or low-voltage AC distribution inside equipment enclosures. Mates with the matching Micro-Fit 3.0 receptacle housing and crimp terminals (sold separately). ## Position Count and Footprint At 4 positions in a dual-row layout, the 430450426 is the smallest position-count member of the Micro-Fit 3.0 header family at this pitch. The dual-row arrangement with 0.118\" (3.00 mm) row spacing gives a compact 0.236\" x 0.118\" footprint for a 2x2 grid — useful where board real estate is tight but the circuit count is low. The 0.125\" (3.18 mm) post length suits standard 1.6 mm PCBs; confirm the board thickness and solder fillet clearance against your assembly stack-up. The active lifecycle means standard lead times apply; no premium for last-time-buy. For BOM matching, the 4-position count and 3.00 mm pitch are the critical fit parameters — confirm the mating half (Micro-Fit 3.0 receptacle) and the crimp terminal wire gauge before committing the line.","metaTitle":"Molex Micro-Fit 3.0 430450426 Header, 4 Pos, 3mm, Gold, 8A","metaDescription":"Molex 430450426 Micro-Fit 3.0 header, 4 circuits, 3.00mm pitch, dual row, through hole, gold mating contacts rated 8A, 600V.
