Typical use is as a mezzanine interconnect or a wire-to-board header when paired with the matching receptacle. The 0.100-inch pitch is the classic breadboard and prototype spacing — it fits standard perfboard and mates with any BergStik II or compatible 2.54 mm receptacle. That plating thickness gives you a solid number of mating cycles for production test or field service without fretting corrosion. The 110 V rating is the working voltage between adjacent pins — fine for logic-level and low-voltage power rails, but derate if you're switching inductive loads near the limit.","metaTitle":"Amphenol FCI 87185-128HLF BergStik II Header, 28 Pos, 2.54mm","metaDescription":"Amphenol FCI BergStik II unshrouded header, 28 positions, 0.100\" pitch, 5A, gold plating.
