Derate above 25°C ambient — the UL94 V-0 housing handles the heat, but the unshrouded pins radiate less than a shrouded header. For power distribution, keep each pin under 3A to stay well below the temperature rise ceiling. The 100 µ\" tin-plated mating finish is thick enough for 50-100 mating cycles in a production or lab environment. Tin is fine for moderate-duty board stacking, but if the assembly sees frequent reconnections or vibration in the field, consider a gold-plated sibling from the same series — tin frets under micro-motion and the contact resistance drifts over time. The 0.100\" pitch and 0.100\" row spacing give a 2.54mm grid that matches standard perfboard and prototyping layouts. The 0.600\" overall contact length with a 0.380\" mating pin means the mated stack height is roughly 0.220\" (5.6mm) plus the receptacle height — confirm the board spacing against the mating half's insulation height.","metaTitle":"FCI 86837-466HLF BERGSTIK II Header, 66 Pos, 0.100\" Pitch","metaDescription":"FCI 86837-466HLF BERGSTIK® II unshrouded header, 66 positions, 0.100\" pitch, 5A, tin-plated.
