4-Pin BERGSTIK® Unshrouded Header — 0.100" Pitch, SMT
The 54202-S0802LF: The unshrouded design gives you direct access to the square pins for wire-wrapping or low-profile board stacking, but it offers no keying — alignment relies on the PCB footprint and mating receptacle.
Surface-Mount Termination and Board Fit
Termination is surface-mount solder — no through-holes, so the board backside stays clear for routing. The tin post finish is compatible with lead-free reflow profiles; the gold mating face resists oxidation in storage or low-current circuits where tin whiskers are a concern.
