Four positions, dual-row, 0.100-inch pitch — a compact signal receptacle
With only 4 positions loaded across two rows, the footprint is small — about 0.200" row spacing and 0.100" between centres — so it fits tight board edges or low-channel-count signal runs. The 0.125" (3.18 mm) post length gives enough standoff for solder fillet inspection on a standard 1.6 mm PCB.
That current ceiling is typical for signal-level circuits — think digital I/O, sensor inputs, or low-power control lines.
