10 positions at 1.25 mm — the space vs current trade-off
The 1-1734261-0 is a 10-position, single-row header on a 1.25 mm pitch, rated 1 A per contact. That pitch is tight enough to save board real estate but limits the current per circuit — if your load per pin exceeds 1 A, you need a wider-pitch header or a parallel row.
Solder retention and surface-mount assembly
The insulation material is UL94 V-0 rated thermoplastic, natural color. For higher cycle life or corrosive atmospheres, consider a gold-plated sibling in the HPI series.
