Half-pitch Low-profile Stacking Connectors XH4A An Integrated Male/ Female Half-pitch Stacking Connector with Board Space Adjustable from 5 to 11 mm. * ■ Board space can be adjusted from 5 to 11 mm in 1-mm increments. (Surface-mounted Connectors can be adjusted from 5 to 9 mm in 1-mm increments.) ■ The product line includes DIP and SMT Connectors. ■ Integrated male/female Connectors. ■ All models incorporate fastening pins to secure the terminals, thus preventing floating or falling over during soldering. ■ The leaf contact construction resists bending. * Excluding SMT connectors ■ The XH4A conforms to UL standards (file no. E103202). (SMT Connectors not included) ■ Not mated with XH2 and XH3 Half-pitch Connec- tors. RoHS Compliant ■ Terminology • SMT The abbreviation of Surface Mount Technology. • Integrated male/female Connectors The male (plug) and female (socket) have the same shape. ■ Ratings and Characteristics Rated current 0.5 A Rated voltage 125 VAC Contact resistance (See note.) 30 mΩ max.

The numbers are in the order shown. • XH4A Half-pitch Connectors are integrated male/female connectors. The contact numbers on row a correspond to the contact numbers on row b. Be careful when using these connectors because they function slightly differently from separate male and female connectors (i.e., Plugs and Sockets). ■ Precautions Mating Compatibility Be sure to wash the board after automated soldering is completed. Correct Use XH4 Half-pitch Connectors do not mate with XH2 or XH3 Half-pitch Connectors. SMT Terminals PCB settings Soldering Conditions XH4A Half-pitch Connectors are male/ female connectors with integrated plugs and sockets. Straight DIP Terminals (Automated Soldering) Refer to Contact Numbers above when designing boards. (2) Continuous soldering time: Within 5±1 s bers are not printed on the connectors. Use the raised reference point used to prevent reverse insertion as a guide when designing boards. (1) Soldering temperature: 250±5°C Recommended reflow conditions Pre-heat temperature: 150±10°C Pre-heat time: 60 to 120 s Soldering temperature: 200 to 240°C Soldering time: Within 30 s (Within 10 s at the maximum temperature of 240°C) Half-pitch Low-profile Stacking Connectors XH4A 5 • Application examples provided in this document are for reference only.
