With a 0.232\" (5.90mm) mating pin length and 0.100\" (2.54mm) insulation height, this header mates with standard low-profile socket strips and leaves enough clearance for a 1.6mm PCB stack. ## Sourcing an Obsolete BERGSTIK® Header The surface-mount solder tails require a solder-paste stencil aperture sized to the 150.0µin tin-lead finish — typical reflow profiles for SnPb solder apply.","metaTitle":"95278-101-40 BERGSTIK® Header, 40 Pos, 0.100\" Pitch","metaDescription":"Amphenol ICC (FCI) 95278-101-40 BERGSTIK® unshrouded header, 40 positions, 0.100\" pitch, SMT, gold GXT™ plating.
