What it is and where it sits in the series
The Molex 430450808 is the 8-circuit member of the Micro-Fit 3.0 43045 series — a dual-row board-to-cable header designed for power and mixed-signal distribution at 3.00 mm pitch. It terminates via solder to the PCB (surface mount, right-angle) and mates with the matching Micro-Fit 3.0 plug housing to complete a wire-to-board harness assembly. The shroud extends four walls around the pin field, and the locking ramp on the header body mates with the receptacle latch to give an audible, positive click — the primary mis-mate prevention feature in harness assemblies. A board-lock foot anchors the connector to the PCB during reflow placement. Dual-plating is the series standard: the mating face carries gold at 30.0 µin (0.76 µm) over nickel, which gives the durability and low contact resistance across repeated matings; the solder-tail side is thick tin at 100.0 µin (2.54 µm), which wets reliably to the pad during SMT reflow without the solubility issues gold presents to solder.
Key ratings and what they mean for the fit
The operating range of -40°C to 105°C covers automotive underhood-class environments at the lower end and enclosed industrial enclosures at the upper end — the LCP housing's glass-fill and UL94 V-0 rating support the thermal and flame-retardance requirements in both markets. The 0.290-inch (7.37 mm) insulation height is the stack-height reference for the mated connector above the PCB surface — it drives keep-out clearance in enclosed assemblies. Confirm the enclosure's z-height budget before selecting the PCB mount.
What mates with it
Packaged on Tape & Reel or Cut Tape for automated SMT placement. The board-lock feature provides retention during reflow; verify paste mask and pad layout against the Molex 43045 series footprint drawing to ensure the lock seats correctly.
