1.00 mm pitch, 3-position SMT header
It's a shrouded header — four walls around the pins — which means the mating receptacle self-aligns and the pins stay protected during handling.
What the shrouding and solder retention mean on the line
The full four-wall shroud guides the mating connector into position — useful when the header is buried inside a tight enclosure or the assembler is working blind. The insulation height is 4.25 mm, and the mated stack height lands at 4.9 mm — a compact profile for low-profile board-to-wire connections.
