Product details

What it is: 28-position unshrouded BERGSTIK

The 77311-101-28LF is the 28-position member of Amphenol ICC (FCI)'s BERGSTIK® single-row unshrouded header line. It carries gold or GXT™ mating contacts rated 3 A per contact, with a through-hole solder termination and a UL94 V-0 thermoplastic insulator rated from -65°C to 125°C.

Selection notes: pitch, plating, and circuit count

At 0.100" (2.54 mm) pitch, the 28-position single-row layout occupies a compact board footprint — the unshrouded design allows mating with standard 0.100" pitch receptacles without a shell keying constraint. The 30.0 µin (0.76 µm) gold or GXT™ mating finish supports repeated mating cycles; the tin-plated post (78.7 µin / 2.00 µm) suits solder joint reliability in wave-solder assembly.
