What this 40-position header does for your board layout
Where this header fits in the AMPMODU Mod II family
The AMPMODU Mod II series covers a range of pin counts and plating options. This 40-position, single-row, tin-plated variant is the high-density end of the single-row breakaway line — the 0.100" pitch and 3A rating are consistent across the series, but the 40-position length demands careful board-edge clearance for the full 4-inch span. Compared to a 10-position sibling, the 40-position version requires a longer PCB keep-out zone and a wider routing channel for the signal traces.
Termination is through-hole solder. The 0.090" post length fits standard 0.062" (1.6mm) PCBs with room for the solder fillet. The square post profile (0.025" nominal) accepts standard crimp receptacles or IDC connectors.
