Product details

3-Pin BERGSTIK® Header at 2.54mm Pitch

The 77311-118-03LF: The 30µin gold over nickel on the mating face supports 500+ mating cycles, making this header a fit for test equipment or modular assemblies that see periodic reconfiguration. Operating temperature spans -65°C to 125°C, covering most industrial and automotive underhood environments where the connector sees no direct spray.

Board Fit and Termination

Unshrouded through-hole header with 0.120" solder posts — the 0.100" pitch matches standard 0.100" grid prototyping boards and production PCBs. Phosphor bronze contacts with 78.7µin tin on the post side — the tin finish is compatible with lead-free reflow profiles and provides a reliable solder joint.
