The 95278-102-72LF: The 0.315" (8.00mm) mating pin length gives enough engagement depth for a typical IDC or crimp socket without bottoming out. Surface-mount termination means the solder tails sit flush on the PCB pads — no through-hole stubs, which keeps the signal path clean for moderate-speed digital or analog signals.

Current Rating and Thermal Budget
The 3A limit is per pin, not per row — the total current through the connector is the sum of all active circuits, but the temperature rise at the housing must be checked against the ambient. At 125°C ambient, the current should be derated per the manufacturer's curve (not shown here).
