It carries 8 A per circuit at a 3.00 mm pitch, with gold-plated mating contacts rated for repeated mating cycles in automotive, industrial, and telecom environments. The 3.00 mm pitch and 0.118\" row spacing define the board footprint — a compact 4-position layout that fits a standard 2x2 grid. The 8 A per circuit rating is the per-contact limit at the rated temperature rise; for a 4-circuit header carrying power, the total current through the connector is 32 A, but each circuit must stay within its individual limit. The 600 V rating provides generous creepage distance for the pitch class, suiting it for 48 V telecom bus or 400 V industrial control panels. Gold mating contacts at 30.0 µin (0.76 µm) handle the mating cycles typical of harness assembly and field service — the gold layer resists oxidation and fretting corrosion better than tin. The tin-plated solder tails (100.0 µin / 2.54 µm) are standard for through-hole wave solder. The shrouded 4-wall housing and UL94 V-0 LCP material make this header suitable for equipment inside an enclosure requiring flame rating. This header mates with the matching Micro-Fit 3.0 receptacle housing (such as the 43025 series) using the standard locking ramp interface. The 4-circuit, 2-row arrangement requires a receptacle with the same circuit count and row configuration.","metaTitle":"Molex Micro-Fit 3.0 430450423, 4 Pos R/A Header, 8 A","metaDescription":"Molex 430450423 Micro-Fit 3.0 right-angle header, 4 circuits, 3.00 mm pitch, gold mating contacts, 8 A, 600 V, UL94 V-0.
