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.

• Contact numbers are not printed on the
connectors. 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.
