Right-Angle Power Header for Board-to-Wire Harnesses
The Molex 430450822 is an 8-circuit, dual-row right-angle male header from the Micro-Fit 3.0 43045 series. It's a board-to-wire interconnect — the header solders into the PCB and mates with a Micro-Fit 3.0 receptacle housing loaded with crimp terminals. The 600 V voltage rating is high for this pitch class — the Liquid Crystal Polymer (LCP) housing and the 4-wall shroud provide the creepage path to support it. This connector is specified for automotive, general purpose, industrial, medical, and telecommunications equipment.
The 8 A per circuit at 3.00 mm pitch means this header carries real power — it's sized for a DC rail or a motor drive line, not a signal bus. The 600 V rating is a system-level spec: the creepage distance between adjacent pins and rows, combined with the LCP housing, holds that voltage without tracking. Derate the current above 105°C per the manufacturer's curve, but for most ambient-temp applications the 8 A is a solid limit. If your application needs frequent field-service reconnections, the gold will hold up; if it's a one-time mate-and-forget, the tin on the solder tails is the workhorse.
This header mates with any Micro-Fit 3.0 receptacle housing — the 8-circuit dual-row version (Molex 430250800 series) is the direct match.
