What it is
The Molex 430450202 is the 2-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, 3.00 mm pitch header with shrouding on all four walls and a locking ramp that audibly snaps into the matching receptacle latch. Rated 8 A per contact at up to 600 V, it is a board-to-cable power header built for industrial and automotive harness environments where the connector sees one-time assembly and is not cycled.
Plating split and what it means
Where this class is used
Micro-Fit 3.0 headers are used as board-to-cable power interconnects across automotive, industrial automation, medical equipment, and telecommunications infrastructure. The shrouded 4-wall design keeps out debris in equipment bays; the board lock feature anchors the header to the PCB during wave soldering and in service vibration. The matching half is the corresponding Micro-Fit 3.0 female receptacle housing with crimp terminals — order the mating pair together to avoid the orphan-plug problem.
