Rated at 1 A per contact and 125 V, this header suits low-power signal connections in automotive, general purpose, industrial, and medical equipment — the 1 A current limit is the practical ceiling for the 1.25 mm pitch and tin-plated contacts.
The 1734260-4 has a 1.25 mm (0.049") mating pitch, single row, 4 positions.
Yes, the 1734260-4 is a surface-mount (SMT) header with solder termination and solder retention features for reflow assembly.
It belongs to the TE Connectivity High Performance Interconnect (HPI) series, a family of compact board-to-cable/wire headers.
The datasheet lists automotive, general purpose, industrial, and medical applications. The 1 A/125 V rating and -25°C to 85°C range suit low-power signal interconnects in those environments.
