The Molex 430452202 is the 22-circuit member of the Micro-Fit 3.0 43045 series, a board-to-wire power header built for harness assemblies that need a positive lock and a secure board anchor. Rated 8 A per circuit at 600 V, with 30.0 µin gold on the mating face and a UL94 V-0 LCP housing, it's specified for automotive, industrial, medical, and telecom equipment where the interconnect sees repeated connect-disconnect cycles and needs to stay mated.
The 3.00 mm pitch and dual-row layout (2×11 positions) give you a compact footprint for a 22-circuit power interconnect — the row spacing is also 3.00 mm, so the board keeps a uniform grid. The 30.0 µin gold on the mating side is a mid-grade plating — enough for hundreds of cycles in a clean environment, and it handles the 600 V rating without creepage issues across the 3.00 mm pitch.
This header mates with the Micro-Fit 3.0 receptacle housings (series 43025) loaded with the matching crimp terminals (series 43030 for 20-24 AWG or 45773 for 18-24 AWG). The shrouded 4-wall shroud and locking ramp are keyed — the receptacle only goes on one way, so you won't mis-mate the harness on the line.
