Tin-over-tin contacts are cost-effective for applications that do not require the corrosion resistance or cycle life of gold — expect reliable performance through a few dozen mating cycles in clean, indoor environments. The unshrouded design (no shroud around the pins) keeps the footprint compact and the header low-profile, but it offers no keying or polarization. The phosphor bronze contacts carry the 5 A rating with adequate spring retention. The 0.120\" (3.05mm) solder post length suits standard PCB thicknesses in the 0.062\" to 0.093\" range.","metaTitle":"Amphenol FCI BERGSTIK II 87052-428HLF, 28-pos 0.100\" Header","metaDescription":"28-position dual-row 0.100\" pitch unshrouded male header, through-hole solder, 5 A per circuit, tin contacts, UL94 V-0.
