2.50mm pitch, 4-position right-angle header with press-fit termination
Termination is press-fit and solder — the press-fit tail eliminates the solder joint for a gas-tight connection in the plated through-hole, reducing process steps and improving reliability under vibration. Rated 3A per contact at 250V, with tin-plated mating surfaces. The 3A ceiling is the thermal limit in still air at 25°C; derate above that temperature per the product drawing.
Press-fit termination and right-angle board mounting
The press-fit termination is a compliant pin that cold-welds to the plated through-hole wall — no solder, no flux residue, and a lower installed cost in high-volume backplane assembly.
The base product number is 440053; the -4 suffix denotes the 4-position variant.
