The 8 A per-circuit rating at 600 V means this header can carry bus-level current on a main DC rail, not just signal lines. The 18 positions at 3.00 mm pitch match a standard 18-circuit BOM line — verify the circuit count against your harness. The UL94 V-0 LCP body handles the temperature rise from 8 A per circuit without softening. This header mates with Micro-Fit 3.0 receptacle housings. The through-hole kinked pins (0.125\" post length) lock into the PCB during wave solder.","metaTitle":"Molex 430451813 Micro-Fit 3.0 Header, 18 Pos, 3mm, 8A","metaDescription":"Molex 430451813 Micro-Fit 3.0 header, 18-position dual-row, 3.00 mm pitch, 8 A per circuit, gold-plated contacts.
