What this is
The Molex 430451612 is the 16-circuit member of the Micro-Fit 3.0 43045 series — a dual-row 3.00 mm pitch header with tin-plated brass contacts rated 8 A per circuit at 600 V, mounted through-hole on the PCB with a kinked pin solder tail. The 4-wall shroud and locking ramp keep the mated pair seated under vibration; the board guide on the housing takes the guesswork out of alignment during assembly. All 16 positions are loaded.
What the ratings mean
Where this connector type is used
Board-to-cable power and signal distribution in harness assemblies — the 600 V rating gives headroom for industrial automation bus structures, and the -40°C to 105°C operating window covers equipment that sees outdoor or unconditioned deployment. The UL94 V-0 LCP housing meets the flame-retardance requirement in most industrial and medical equipment enclosures. Telecommunications infrastructure and general-purpose industrial controls are the primary application areas listed.
