Product details

The Molex 0430450424 is a 4-circuit, dual-row header from the Micro-Fit 3.0 43045 series. It is a board-to-cable/wire interconnect, designed for applications in automotive, general purpose, industrial, medical, and telecommunications equipment. The 3.00mm pitch and 0.118" row spacing give enough creepage for the 600V rating without forcing an oversized board footprint.

Key Features and Ratings

Rated 8A per circuit at 600V, this header carries enough current for moderate power distribution in a harness assembly. The through-hole termination with kinked, solder pins ensures a secure mechanical hold on the PCB.

Mating and Sourcing

For a complete connection, order the receptacle and the appropriate crimp terminals for your wire gauge.
