80 Positions on 0.100" Pitch — Board Fit and Density
In a high-vibration environment, a shrouded header (like the 953440-3) would provide better polarization and latch retention.
3 A per Contact — Signal-Duty Current Ceiling
For a 80-position header carrying 3 A on every circuit, the total board-level current is 240 A — the limiting factor is the trace width on the PCB, not the connector.
