1.80 mm pitch, 3-position SMT header for low-voltage signal duty
The 2080353034: This Molex CONNTAK50 header carries 3 positions in a single row on a 1.80 mm pitch — the tightest footprint in this series, which means the board layout engineer needs to route traces between 0.071-inch centers. The surface-mount termination with pick-and-place features lets it run through a standard reflow oven without extra handling. The 14 VAC/DC rating and current limited by wire gauge tell you this is a signal or low-power interconnect, not a power bus.
