0.100" Pitch, 8-Position Unshrouded Header — Board Layout Fit
The 77311-118-08LF: The through-hole termination and 0.230" (5.84 mm) mating pin length give a solid mechanical anchor for wire-to-board or board-to-board connections where the header is soldered directly to the PCB.
30.0 µin Gold Mating Finish — Reconnect Duty Without Fretting
In a test fixture or a modular board that gets reconfigured quarterly, that gold thickness keeps contact resistance stable and avoids the tin-whisker risk that can appear on tin-only finishes in high-humidity environments.
