Surface-mount solder tails with tin post finish (50.0µin) wet well with standard SAC305 reflow profiles. The Pick and Place feature means the flat shroud top accepts a vacuum nozzle, so this header feeds directly into an SMT line without a special feeder or nozzle change. In a low-vibration environment like a mezzanine stack inside an enclosure, this is adequate; for high-shock applications, consider a header with a locking ramp.","metaTitle":"20021221-00020C4LF Pin Header 20POS 1.27mm SMT Amphenol ICC","metaDescription":"20021221-00020C4LF Amphenol ICC Minitek127® 1.27mm SMT header, 20 positions, gold mating finish, shrouded 4-wall, rated 1A/125VAC.
