The FX10A-120S/12-SV(71) is a 120-position 0.5mm female Stacking Board Receptacle with beige LCP insulator, gold plated phosphor bronze contacts, tin plated phosphor bronze ground plate and tin plated phosphor bronze metal fitting. Transmission characteristics have been improved through a design that fixes ground plates to both sides of the header and receptacle. Signal and ground contacts are arranged in a 10:1 ratio. The ground plate is connected to the board and the resulting ground stability effectively reduces noise. The 0.5mm signal contact pitch provides a smaller overall connector, using less mounting area on the board. An alternate style without the ground plate is available. The space provided by the ground plate removal has been filled with additional signal contacts. The insertion-loss-to-crosstalk-ratio (ICR) with five-aggressor differential FEXT meets the extrapolated IEEE 802.3ap specification for 15+Gbps.
