Right-Angle SMT Header for Tight Board-to-Wire Links
The 10114830-13103LF: The gold handles repeated mating cycles in low-current signal paths; the tin tail wets reliably during reflow.
What the Gold Plating and Current Rating Mean on the Floor
In a connector that gets cycled quarterly, that's decades of reliable contact resistance. The 1 A rating is conservative for a 1.25 mm pitch header. For signal-level currents (0.5–1 A), the derating curve is flat; push past 1 A and the housing material becomes the ceiling.
How This Header Compares to Its Siblings
The 10114830-13103LF carries gold on the mating face (30 µinch). The sibling 10114830-10103LF is otherwise identical but uses tin on the mating contact — a cost-down option for applications with few mating cycles. The 10114830-11103LF also has gold, but only flash thickness, not the full 30 µinch. For high-cycle or corrosive environments, the 13103LF's thicker gold is the right call. The 10114830-10104LF is a 4-position version of the tin-plated variant — same pitch, same orientation, same current rating. If the BOM calls for 3 positions, the 13103LF is the match; if the circuit count changes, the 4-position sibling is a drop-in footprint.
