For designs that require repeated field service or frequent reconnection, a gold-plated BergStik variant is the better choice. Derate current above 25°C ambient per the product drawing; the wide temperature range means the connector can operate at 125°C, but the current must be reduced accordingly. ## Mating, Mounting, and Orientation The header is loaded in all 18 positions, so the full complement of pins is present. The square male pin contact shape provides a reliable gas-tight interface with the receptacle's female contact. For board-to-board stacking, the mated stack height depends on the receptacle chosen — typical BergStik receptacles add 0.100\" to 0.200\" to the overall height. The base product number is 95278, which covers the BergStik SMT header family. The -401-18LF suffix specifies the 18-position, tin-plated, SMT variant.","metaTitle":"95278-401-18LF Amphenol ICC (FCI) BergStik 2-Row SMT Header","metaDescription":"95278-401-18LF BergStik unshrouded header, 0.100\" pitch, 18 positions, 2 rows, SMT, tin-plated contacts, 3 A, UL94 V-0.
