FCI 86503-112HLF BERGSTIK II Header, 12 Pos, 0.100" Pitch

Rated 5A per contact with 30.0µin (0.76µm) gold plating on the mating surface, this header is specced for repeated mating cycles and moderate current levels — think power distribution on a backplane or a board-to-wire harness interface, not just a low-level signal line. The gold thickness is enough to resist fretting corrosion in environments with thermal cycling or vibration, provided the mating receptacle uses a compatible gold-on-gold interface. The mating receptacle housing must provide the keying and latch retention; the header itself offers only a push-pull interface. The 0.100" (2.54mm) row spacing mirrors the pin pitch, so the overall footprint is a 2x6 grid that fits a standard 0.100" x 0.100" prototyping area. The phosphor bronze contacts with the stated gold plating are a common combination for a balance of cost and cycle life in commercial and industrial gear.
