20-Position Shrouded Header for Board-to-Board Stacking
The 20021221-00020C4LF: The 0.050" (1.27mm) pitch and 0.050" row spacing give a compact footprint while keeping enough room for trace routing between pads on a standard PCB.
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.
