Rated at 8 A per circuit with a 600 V voltage rating, each power blade carries enough current for a moderate DC rail or a bank of I/O. The tin-plated solder tails (100.0 µ\") handle the reflow side without issue. This header mates with the matching Micro-Fit 3.0 receptacle housing (sold separately), which accepts the standard Micro-Fit 3.0 crimp terminals for 20-24 AWG wire. Termination is solder-only — the SMT tails are designed for reflow assembly. The solder retention feature holds the part in place during the solder paste reflow, preventing tombstoning or skew from the shear force of a cable strain. No press-fit option exists for this variant.","metaTitle":"Molex Micro-Fit 3.0 430451411, 14-Pos Header, 3mm Pitch, 8A","metaDescription":"Molex 430451411 Micro-Fit 3.0 header, 14 circuits, dual-row, 3.00mm pitch, right-angle SMT, gold-plated contacts, 8A, 600V, UL94 V-0.
