What the 18-Circuit Single-Row Layout Means for Your Board
The 1-103908-7: Eighteen positions all loaded, single row: the routing is straightforward, and the 0.130" (3.30 mm) post length gives a solid solder joint through a standard 1.6 mm board. The latch holder fastening provides positive retention — in a vibration environment like automotive or industrial equipment, this prevents the header from backing out of the receptacle.
Gold Plating and Contact Reliability
The brass contact material provides good conductivity and spring properties.
Mating and Termination Compatibility
Termination is press-fit or solder — the press-fit option suits backplane assembly where rework is needed; solder gives a more permanent joint for cable-to-board applications.
