Frequently asked questions
What is the pitch of the 77313-120-12LF and what does it mean for board layout?
The pitch is 0.100 inch (2.54 mm) — standard 2.54 mm grid spacing common across the BERGSTIK series and most DIP-compatible pin headers, meaning it fits standard 0.100 inch pitch through-hole footprints and aligns with common routing channel widths on two-layer boards.
What is the contact finish on the 77313-120-12LF and why does it matter?
The mating interface carries gold or Gold GXT plating at 30.0 µin (0.76 µm) over the phosphor bronze base; the solder post is tin at 78.7 µin (2.00 µm). Gold on the mating side extends cycle life and maintains low contact resistance at first mate — the tin tail keeps solder assembly straightforward and cost-effective.
