FX11 B2B Connectors with Ground Plate

Hirose FX11 Series B2B Connectors are 0.5mm pitch headers and receptacles with optional ground plates on both sides of the header and receptacle to improve transmission characteristics. Signal and ground are arranged in a ratio of 10:1 with the ground plate SMT connected to the board. The ground stability achieved serves to reduce noise. The FX11 is structured to prevent solder wicking via a solder gap in the contact SMT portion. With a stacking height of either 2mm, 2.5mm, or 3mm, the FX11 series comes in 60, 80, 100, or 120 contact positions, provides additional solder weld strength through metal fittings.
