FunctionMax™ FX8C Header for Dense Mezzanine Stacking
The Hirose FX8C-140P-SV(92) is a 140-position header from the FunctionMax™ FX8C series, designed for high-density board-to-board mezzanine connections. It uses a 0.024" (0.60mm) pitch across two rows, which forces tight trace routing and small via geometries on the PCB — plan the fanout early. The outer shroud contacts and integrated board guide help align the mating halves during assembly, taking shear off the signal pins. Surface mount termination suits automated pick-and-place lines.
