The TE Connectivity 5-1971846-3 is a 3-position, single-row RAST 5 tab header on a 5.00 mm pitch. Rated 20 A per circuit at 250 VAC, this is a power-level interconnect for board-to-cable/wire applications in appliances, industrial controls, and lighting.
The silver plating on both the mating contact and the solder post is a step up from tin: silver carries the 20 A rating with lower contact resistance than tin at this current level, though it tarnishes more readily in high-humidity environments. The glow wire compliant feature means the housing material passes the IEC 60695-2-11 glow-wire test, a requirement for unattended appliances and white goods where the connector sits near a potential ignition source.
