It's a board-to-wire interconnect — a right-angle through-hole male pin header that mates with the matching Micro-Fit 3.0 receptacle housing and crimp terminals. The 3.00 mm pitch and 0.118\" row spacing define the PCB footprint; the 8 A per-circuit rating means each contact can carry genuine power, not just signal-level current. Gold plating on the mating side (30.0 µin) handles repeated connect-disconnect cycles without the fretting corrosion you'd see with tin on a frequently serviced harness. ## Key Features That Drive the Fit The locking ramp secures the mated pair against vibration — it's the same latch used across the Micro-Fit 3.0 family, so the receptacle housing clicks in with an audible lock. The board lock holds the header in place during wave solder and resists the shear force from cable strain after assembly. The 4-wall shrouding protects the pins from damage during handling and guides the receptacle into alignment. The right-angle orientation routes the cable parallel to the board, saving z-height in shallow enclosures. ## Applications and Environments This header is listed for automotive, general purpose, industrial, medical, and telecommunications applications. The -40°C to 105°C operating range covers automotive underhood and industrial cabinet environments. The UL94 V-0 rated LCP housing is flame-rated for equipment inside an enclosure — a compliance requirement for medical and industrial builds.","metaTitle":"Molex 430450402 Micro-Fit 3.0 Header, 4 Pos, 3mm Pitch, 8A","metaDescription":"Molex 430450402 Micro-Fit 3.0 header, 4 positions dual-row, 3.00 mm pitch, right-angle through-hole, gold contacts, 8 A, 600 V, board lock.
