Current, Plating, and Contact Duty
The 20021121-00010D4LF: The mating interface carries 10 µinch gold over copper alloy — this is a signal-grade finish suited for moderate mating cycles (50–100 cycles typical). For applications requiring higher durability, the sibling 20021121-00010D8LF uses 30 µinch GXT™ plating, which extends cycle life to 500+ mates. The solder tails are tin-plated (50 µinch) — compatible with standard SAC305 solder paste and reflow profiles.
SMT Assembly and Pick-and-Place
The tube packaging feeds into standard tray shuttles; if you need tape-and-reel, check the sibling 20021121-00010T4LF which shares the same footprint and plating.
