What it is
The Molex 430450606 is a 6-circuit dual-row Micro-Fit 3.0 header in the 43045 series — 0.118" (3.00 mm) pitch, right-angle surface-mount, with square male pins that mate with the matching Micro-Fit 3.0 receptacle housings used in board-to-cable harness assemblies. Contact finish is tin over the full mating interface at 60.0 µin (1.52 µm) thickness — the standard tin plating grade for this series, which suits permanent or low-cycle field installation rather than repeated reconnect duty.
Key ratings and what they mean
Rated 8 A per circuit at 600 V — the 600 V rating supports board-to-wire power distribution in industrial automation and automotive harness applications. The 4-wall shrouding with locking ramp physically keys the mated pair and resists vibration back-out — the ramp locks before the housing clicks fully home, so the assembler gets a positive pre-load signal before final seat. Board lock feature holds the header during SMT reflow without a separate clip or adhesive — relevant for automated assembly flows where coplanarity and tombstoning risk are managed by the mount itself. Insulation height is 0.290" (7.37 mm); the LCP glass-filled housing carries a UL94 V-0 flammability rating, which satisfies most industrial and automotive interior panel requirements without a separate flame-barrier note. Operating range -40°C to 105°C covers the full automotive and industrial panel temperature band — no de-rating action required within that window at the rated 8 A per circuit.
Where it is used
Board-to-cable power and signal interconnect in automotive harness modules, industrial control panels, and medical device enclosures — the 6-position count maps to typical low-circuit分支 nodes like sensor feeds, indicator clusters, or actuator control lines rather than high-density bus routing.
