XH3A-3041-4A
XH3 Half-pitch Board-to-Board Connectors Screw Mount Eliminated to Save Space. Adjustable Stacking Space of 12 to 20 mm Adds Greater Flexibility. ■ The stacking space can be adjusted from 12 to 20 mm in 1-mm increments. ■ A pitch of 1.27 mm for high-density mounting in double-row arrangements. ■ A quadruple-row staggered arrangement (1.27 x 1.905 mm) for board connection. ■ All models incorporate fastening pins to secure the terminals, thus preventing floating or falling over during soldering. ■ Leaf contact construction enables smooth mating and resistance to bending. ■ Space saving mating length of 3.1 mm. ■ Press fitting assures long-term contact quality. The gold/palladium plating has been improved for better contact reliability. ■ The XH3 conforms to UL standards (file No. E103202). ■ Not mated with XH2 and XH4 Half-pitch Connectors. RoHS Compliant ■ Terminology • Standard To vertically connect the printed-wiring board, connect the socket straight terminal connector to the mother board (main board) side and connect the plug right-angle terminal connector to the daughter board (sub board) side. • Reverse To vertically connect the printed-wiring board, connect the plug straight terminal connector to the mother board (main board) side and connect the socket right-angle terminal connector to the daughter board (sub board) side. • Stacking Connects the printed-wiring boards parallel to each other. The distance between the boards here is called "stacking height". • Horizontal Connect the printed-wiring boards horizontally. • Leaf contact construction In this structure, contacts are protected by the housing. Mating figure of the XH3A/XH3B The contacts are protected by the housing when mated so that they do not readily deform. ■ Ratings and Characteristics Rated current 0.5 A Rated voltage 125 VAC Contact resistance (See note.) 30 mΩ max. (20 mV max., 100 mA max.) Insulation resistance 1,000 MΩ min. (at 500 VDC) Dielectric strength 650 VAC for 1 min (leakage current: 1 mA max.)
