MLX 36759 15-Circuit Power Header
The Molex 367590147 is a 15-circuit, 3-row header from the MLX 36759 series, designed for board-to-cable/wire power interconnects. It carries a 9A per circuit rating at a 0.250" (6.35mm) pitch, with a 600V voltage rating that suits industrial power distribution within an enclosure. The through-hole solder termination and tin-plated contacts (137.8µin on both mating and post sides) make this a straightforward, production-ready part for harness assemblies where the locking ramp provides vibration-resistant retention.
What the Ratings Mean for Fit and Duty
The 0.250" (6.35mm) pitch sets the board footprint — trace width and clearance for the 600V rating are straightforward at this spacing, and the 3-row layout packs 15 positions into a compact through-hole pattern. The 9A per circuit is a power-class rating; this header is sized for the main DC rail or motor drive lines, not signal-level duty. The tin plating (137.8µin on both mating and post surfaces) is adequate for the current density and for applications with moderate mating cycles — gold is not required here because the contact force at this pitch handles the current without fretting concerns.
Mating and Termination
This header mates with the matching MLX 36759 receptacle housing (female socket contacts, circular contact shape). The locking ramp on the header engages with the housing latch for positive retention in vibration-prone environments. Termination is through-hole solder — the 0.170" (4.32mm) post length fits standard PCB thicknesses. The 3-row arrangement means the mating housing carries 15 circuits in the same 0.250" row spacing, so the wire harness side must match this row count and pitch exactly.
