Connector Types

Board-to-board (BTB), wire-to-board (WTB), FPC/FFC, USB/HDMI, power connectors and high-speed backplane connectors each suit specific applications.

Key Parameters

Pitch (0.5mm-5.08mm), contact plating (gold for reliability, tin for cost), current rating, voltage rating, mating cycles and operating temperature.

High-Speed Considerations

For PCIe/SAS/Ethernet, choose connectors with impedance control and signal integrity specs; verify insertion loss and crosstalk in design.

Sourcing

Connectors from JST, Molex, TE, Hirose and domestic makers have long lead times in some families. HuaXinGou sources connectors with original packaging and batch traceability.
