FX10 B2B Connectors with Ground Plate

Hirose FX10 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. With a stacking height of either 4mm or 5mm, the FX10 series comes in 80, 100, 120, and 140 contact positions. provides additional solder weld strength through metal fittings. Hirose's FX10 Series B2B Connectors without the grounding plate have been filled with additional signal contacts (96, 120, 144, and 158 contact positions). These board-to-board connectors feature a rated current of 0.3A and a rated voltage of 50VAC. Ideal for notebook computers, PDA, and other miniature electronic equipment.
