The tin-plated posts accept standard solder paste profiles. The phosphor bronze contacts provide good spring retention over that range without stress relaxation. The tin plating and thermoplastic housing are lead-free per the directive.","metaTitle":"95278-401-32LF Amphenol BERGSTIK Header 32-Pin 2.54mm SMT","metaDescription":"95278-401-32LF Amphenol ICC BERGSTIK 32-position unshrouded header, 2.54mm pitch, tin plating, SMT.

The key difference is termination style — this is surface mount; through-hole versions exist under the same base number 95278.
