The 0.095\" (2.41 mm) solder post length suits standard 1.6 mm PCBs; the 1.043\" (26.49 mm) mating pin length gives ample reach into a mating receptacle. The 5 A per-contact rating is derated by the UL94 V-0 housing material's temperature ceiling — in practice, stay below 3.5 A per circuit for continuous duty across all 28 positions to keep the temperature rise within the thermoplastic's limits.","metaTitle":"FCI 87185-428HLF BERGSTIK II Header, 28-Pos, 0.100\" Pitch","metaDescription":"FCI BERGSTIK® II unshrouded header, 28 positions, 0.100\" pitch, through-hole, tin-plated, rated 5A at 110V.
