What the 0.250" pitch and 5 positions mean for your board
The 0.250" (6.35 mm) pitch sets the board footprint and the per-contact current ceiling — at the series' typical 5 A rating, the temperature rise stays within the nylon housing limit. The single-row layout keeps the board-edge footprint narrow, useful for tight enclosure layouts.
Tin-plated contacts and through-hole termination
The through-hole solder termination (contact length 0.155" / 3.94 mm) provides a robust mechanical anchor on the PCB, suitable for wire-to-board connections where the cable exerts pull force on the header.
