It's a board-to-cable/wire style connector, meaning the header stays on the PCB and mates with a crimp-terminated receptacle housing. The contacts are tin-plated phosphor bronze, rated 1A per circuit at 125V. Tin plating is fine for moderate mating cycles (50-100 mates) in clean environments; the 150 microinch thickness gives some margin against fretting corrosion in mildly corrosive atmospheres. The 1A limit is a signal-level current — think sensor inputs, logic-level power, or low-current actuator drives. That covers automotive cabin, industrial enclosures, and medical equipment that isn't autoclaved. The three-wall shroud protects the pins during blind mating — a real help on a harness assembly line where the operator is plugging by feel. ## SMT Termination and Solder Retention Surface-mount termination means this header is placed by pick-and-place and reflow-soldered. No through-hole soldering or wave solder step needed.","metaTitle":"1734260-3 TE Connectivity 1.25mm Header SMT 3-Pin - Buy","metaDescription":"1734260-3 TE Connectivity AMP Connectors High Performance Interconnect (HPI) header. 3 positions, 1.25mm pitch, 1A, 125V, SMT, shrouded.
