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.

Use the triangular mark (▼) as a guide when designing and mounting to boards. • On the mating side, the row of terminals on the triangular mark side are called row a, and the row on the other side is called row b. The numbers are in the order shown. ■ Precautions Automated Soldering Conditions (Jet Flow) Correct Use 1. Soldering temperature: 250±5°C 2. Continuous soldering time: Within 5±1 s (Be sure to wash the board after continuous soldering is completed.) Mating Compatibility • The triangular marks on the plug and socket must be aligned when mated. The contact numbers on both sides must match. XH3 Half-pitch Connectors do not mate with XH2 or XH4 Half-pitch Connectors. Flux Rise These Connectors were designed for automatic soldering. If you use a foaming device or brush on flux from the front side, the amount of applied flux will increase and may cause flux rise. Do not use these methods to apply flux. Soldering Automated soldering Use tape to mask the Right-angle Terminal Connector prior to automated soldering.
