The 1-382811-6: The open-top profile lets you probe the circuit or visually confirm the jumper position without removing the shunt. Gold plating at 15.0µin on the female sockets gives reliable low-resistance contact across repeated mating cycles, suitable for configuration headers, test points, and programming jumpers where corrosion resistance matters.
Pitch and footprint match
The 0.250" (6.35mm) height clears most surrounding components on the board. The 2-position single-row layout (1 x 2 grid) mates with two adjacent pins on a matching header. No keying or polarization — orientation is symmetric.
