It carries 8 A per circuit at 600 V on a 3.00 mm pitch, with gold-plated mating contacts (15.0 µ\" thickness) for corrosion resistance over repeated mate cycles. Within the Micro-Fit 3.0 family, the 20-position 430452019 sits between the 16-position 430451610 and the 24-position 430452419 at the same 3.00 mm pitch. The 20 positions match a 20-circuit BOM line; the dual-row layout keeps the board footprint compact at roughly 30 mm long by 9.91 mm tall off the board.","metaTitle":"Molex Micro-Fit 3.0 430452019, 20-Position SMT Header","metaDescription":"Molex Micro-Fit 3.0 430452019 20-position dual-row SMT header, 3.00mm pitch, 8A/600V, gold-plated contacts, shrouded 4-wall.
