Product Description
This USB 2.0 Type-A female PCB connector is designed for reliable
power and signal transmission in compact electronic equipment. The
connector uses a PBT glass-fiber housing and a nickel-plated
stainless-steel shell to deliver high mechanical strength and
excellent resistance to heat and corrosion, making it suitable for
long-term operation in demanding environments. Gold-flash contacts
and tinned terminals ensure stable contact resistance and low
electrical loss for both power and high-speed data lines.
The through-hole DIP termination provides strong solder joints on
the PCB and improves retention strength compared with SMT-only
solutions, especially in applications where the mated cable may be
frequently plugged and unplugged. The standard 4-pin USB layout
supports USB 2.0 data transmission while remaining
backward-compatible with many existing cable assemblies and host
interfaces.
This connector is ideal for use in power banks, smart chargers,
consumer electronics, industrial controllers, communication
equipment, automotive infotainment modules, and other devices that
require a robust electrical connector between a USB cable and the
PCB.

Precautions
Electrical rating – Do not exceed the specified current and voltage; overspec
loading may cause overheating of the connector and surrounding PCB
pads.
PCB layout – Follow the recommended land pattern and keep high-speed signal
traces short and impedance-controlled to maintain stable
transmission quality.
Soldering process – Suitable for wave-solder or selective-solder processes. Avoid
excessive solder temperature or dwell time to prevent deformation
of the PBT housing.
Mating compatibility – Use with standard USB Type-A male plugs and quality cables to
ensure proper insertion force and contact alignment.
Mechanical stress – Avoid pulling or twisting the mated cable at extreme angles; use
strain-relief structures or cable clamps in the enclosure design.
Environment – Keep away from corrosive gases, conductive dust, and
condensation. For outdoor or high-humidity use, consider sealing or
conformal-coating the PCB area.
This structure can be directly used as the product section in your
own website or on Made-in-China, and you can adjust ratings or
options to match specific customer drawings or customized versions.
