34-position BERGSTIK breakaway header
The 98401-802-34LF is the 34-circuit member of Amphenol's BERGSTIK unshrouded breakaway header line, configured as a board-to-board interconnect. It carries gold GXT mating contacts rated 3 A and mounts surface-mount with solder termination across a 0.100" (2.54 mm) pitch.
Pitch, footprint, and plating choices
The 0.100" (2.54 mm) pitch and 0.100" (2.54 mm) row spacing set a standard footprint that matches the BERGSTIK series board layout — the breakaway design allows snapping to the required circuit count. Mating contacts are gold GXT with 15.0 µin (0.38 µm) thickness; post contacts are tin-lead with 150.0 µin (3.81 µm). The phosphor bronze contact material and UL94 V-0 thermoplastic insulation support an operating range of -65°C to 130°C.
