What it is
The Molex 430452213 is the 22-circuit member of the Micro-Fit 3.0 43045 series — a dual-row, shrouded header rated 8 A per contact at 600 V, with a kinked-pin through-hole termination and a locking ramp that secures the mating receptacle against vibration. All 22 positions are populated. The dual-beam square-pin contact geometry is sized for the matching Micro-Fit 3.0 female crimp housing; the 4-wall shroud prevents mis-mate in dense harness runs.
What the ratings mean
At 8 A per circuit in a 3.00 mm pitch body, the 430452213 sits in the upper current band for this series — the 100.0 µin (2.54 µm) tin plating on the solder tails is ample for wave or hand-solder board assembly, while the 15.0 µin (0.38 µm) gold on the mating face governs the plug-in interface durability. Gold thickness on the mating side is the primary driver of mating cycle life in this plating split; the LCP housing carries a UL94 V-0 flammability rating, making it suitable for automotive and industrial enclosures where flame-retardance is specified. Operating range is -40°C to 105°C, and the 0.390 in (9.91 mm) insulation height gives the header adequate standoff from the PCB surface for board-wash or conformal coat clearance.
