This keeps the board-side footprint small — the insulation height is only 0.098 inches (2.50 mm) above the board surface. ## Tin-plated contacts at 118.1 µinch — cost-optimized duty Both the mating and post finishes are tin, plated to 118.1 µinch (3.00 µm). Tin is a reliable, low-cost contact finish for moderate mating-cycle applications in clean, indoor environments. It does not match the cycle life of gold, but at this thickness it resists oxidation well for typical board-to-wire interconnects in automotive and general-purpose equipment. The contact base is brass — a standard spring material for pin headers. The square pin shape (0.025-inch square typical for 2.54mm pitch) provides a consistent four-point interface with the receptacle terminal.","metaTitle":"Molex 0901310140 C-Grid III Header, 40 Pos, 2.54mm Pitch","metaDescription":"Molex 0901310140 C-Grid III 90131 series, 40-position, 2.54mm pitch unshrouded breakaway header, tin plating, UL94 V-0.
