It carries a 3.00 mm pitch on both rows and a row-to-row spacing of 3.00 mm, which keeps the PCB footprint compact while maintaining sufficient creepage for the 600 V rating. Rated at 8 A per circuit, this header handles moderate power distribution — think internal harnesses in automotive, industrial control cabinets, or telecom equipment. ## Through-Hole Termination and Packaging for the Line Termination is through-hole with kinked pins. The header ships in tray packaging. For high-volume pick-and-place lines, tray-to-tube or tray-to-reel conversion is common — factor that into your line feed planning if you are running reel-fed headers elsewhere on the same build. The housing is black LCP, glass-filled, rated UL94 V-0. ## Comparison with the 16-Position Sibling Against the 16-position member of the same series (430451610), the 430452026 adds 4 positions at the same 3.00 mm pitch and row spacing. The 20-position version extends the header length by 12.00 mm (4 positions × 3.00 mm) on the same footprint width — the board layout keep-out zone widens accordingly, but the mounting hole pattern and row-to-row spacing are identical.","metaTitle":"Molex Micro-Fit 3.0 430452026 Header, 20 Pos, 3mm, 8A","metaDescription":"Molex 430452026 Micro-Fit 3.0 header, 20-position dual-row, 3.00mm pitch, 8A per circuit, gold contacts, 600V, shrouded, board lock, active.
