For power delivery above 3 A per circuit, step up to a higher-current series. This is a standard plating for moderate mating cycle counts — typically 100–200 cycles — and offers corrosion resistance in non-sealed environments.
Sourced through independent distribution channels. The part ships in a bag — not tape-and-reel — so plan for manual placement or a tube feeder if running automated assembly.
