Board-to-Board Header, 11 Circuits, 0.100" Pitch
It uses the industry-standard 0.100" (2.54 mm) pitch, making it footprint-compatible with a wide range of breadboard and prototype layouts, as well as production PCBs designed for this grid.
The 5 A per circuit rating at 110 V is conservative for a tin-plated contact of this size; the limiting factor in practice is the temperature rise in the housing, which the UL94 V-0 black insulation handles without issue in enclosed equipment. The 100.0 µin (2.54 µm) tin plating on the mating surface is thick enough for a moderate number of mating cycles in a permanent or semi-permanent install. Tin is not rated for the high-cycle duty of gold — expect reliable performance for assembly and occasional field service, not repeated connect-disconnect in a test fixture.
This unshrouded header mates with any standard 0.100" pitch single-row receptacle housing that accepts 0.025" square pins. For a wire-to-board application, pair it with a crimp-to-wire receptacle housing and matching crimp terminals. The 0.128" solder post length is designed for standard 0.062" thick PCBs; for thicker boards, verify the post protrudes enough for a reliable solder fillet.
