3-Position Power Header for Press-Fit Backplane Assembly
Press-fit termination eliminates the need for soldering, making this header a fit for high-reliability backplane assemblies where rework and field replacement are factors. The silver contact finish is typical for power-grade contacts — it handles higher current densities than tin or gold flash, though the exact current rating should be confirmed from the manufacturer's derating curve for the specific application.
The press-fit termination requires a PCB with plated through-holes sized to the manufacturer's recommended hole diameter and finished thickness — the press-fit zone is designed for a controlled interference fit that cold-welds the pin to the barrel without solder. The single-row, 3-position layout is loaded all positions.
