High-Speed SAS 4.0 29 Pin SMT Female Connector, 30U" Gold-Plated electricial

This SAS 29P SMT Female Connector is designed for high-speed electronic signal and power transmission in demanding server, storage and automotive systems. The connector adopts 30U" gold-plated contacts over 50U" nickel underplating, delivering excellent conductivity, corrosion resistance and long-term signal integrity. Solder tails are finished with 80U" matte tin over nickel, ensuring reliable wetting and strong joints on the PCB.

The connector uses a glass-filled LCP housing and cap (UL94-V0), offering high mechanical strength and heat resistance during SMT reflow soldering. Phosphor bronze C5191-H terminals provide stable contact force and durability throughout the product’s service life.

A positioning peg and fishhook-style latch help the connector sit accurately on the PCB and lock firmly into the mating plug, improving vibration resistance and assembly efficiency. Electrical performance includes 1.5A @ 40VAC per contact, ≤30mΩ contact resistance, ≥1000MΩ insulation resistance, and 500 mating cycles tested per EIA 364-09, making it suitable for continuous, high-reliability operation.

With HF + RoHS 2.0 compliance, this connector supports environmentally friendly manufacturing while meeting global industry standards, and is fully SAS 4.0 compatible for next-generation storage and server platforms.

⚠️ Notes

• Design the PCB pads and stencil openings according to the SMT footprint recommended in the drawing to ensure proper solder fillet and coplanarity.
• Follow a suitable reflow temperature profile compatible with LCP UL94-V0 materials to avoid deformation or discoloration.
• Keep contact areas clean and free from dust, oil or oxidation before mating; avoid touching terminals directly by hand.
• Do not exceed the specified mating/unmating forces and 500-cycle endurance to maintain terminal integrity and stable contact resistance.
• Store products in dry, anti-static packaging; use ESD-protected workstations when handling and assembling the connectors.
• Avoid corrosive environments beyond the specified 48-hour salt spray performance and respect the rated current/voltage to guarantee long-term reliability.
