4-circuit single-row header with shrouded locking
The 0436500405 is the 4-circuit single-row member of Molex's Micro-Fit 3.0 43650 header family, a board-to-cable/wire interconnect. Gold-plated mating contacts (30.0µin / 0.76µm) and a shrouded 4-wall housing with locking ramp provide secure retention for power and signal duty in general-purpose, medical, military, and telecommunications equipment.
Board lock and right-angle mounting
Through-hole right-angle mounting with integrated board locks holds the header in place during wave solder — the 0.125" (3.18mm) post length suits standard PCB thickness. The 0.118" (3.00mm) pitch and single-row layout keep the board footprint compact; the UL94 V-0 LCP housing resists process temperatures.
