What this 4-position SMT header does for your board
Rated at 125VAC, with current capacity that varies by the wire gauge of the mating crimp terminal. The tin-on-tin contact finish is a workhorse choice for moderate mating cycles in general-purpose environments.
Detent lock and SMT retention for production reliability
The detent lock gives a positive tactile click when mated with the matching CT receptacle — no secondary latch needed, but the hold is enough to keep the pair together under light vibration. Surface-mount termination means this header is reflow-compatible, saving a wave-solder pass.
