XH3 Half-pitch Board-to-Board Connectors

Screw Mount Eliminated to Save Space.Adjustable Stacking Space of 12 to 20mm 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 × 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.

Correct Use

Mating Compatibility

XH3 Half-pitch Connectors do not mate

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.

Automated Soldering Conditions (Jet Flow)

1. Soldering temperature: 250±5℃
2. Continuous soldering time: Within 5±1 s (Be sure to wash the board after continuous soldering is completed.)
