Frequently Asked Questions
What is the Minimum Order Quantity (MOQ) for this USB 3.0 connector?
As a direct manufacturer, our standard MOQ for this specific receptacle is typically 1,000 to 5,000 pieces depending on the packaging type (tape & reel vs. tray). However, we can accommodate smaller batch orders for your initial prototyping and engineering validation phases.
Can we customize the gold plating thickness on the contact pins?
Yes. The standard model comes with gold flash plating. For applications requiring higher durability or exposure to harsh environments, we offer custom plating options including 15µ", 30µ", or thicker gold plating to extend the mating cycles and prevent corrosion.
Are these connectors RoHS and REACH compliant?
Absolutely. All our USB connectors and cable assemblies are manufactured using eco-friendly materials and are fully compliant with the latest RoHS and REACH directives required by the US and European markets.
Do you provide 3D CAD models to help with our PCB layout?
Yes, we provide 3D STEP files, 2D technical drawings, and recommended PCB footprint files upon request. Our engineering team can also assist with design-in support to ensure perfect alignment with your enclosure.
What is the typical lead time for volume production?
Once prototyping is approved, standard lead times for volume production range from 2 to 4 weeks. We also keep safety stock for our long-term OEM partners to ensure uninterrupted supply chain operations.
What is the benefit of the wide operating temperature range (-55°C to +105°C)?
Standard consumer USB ports are only rated for -40°C to +85°C. Our connector uses high-grade insulator plastics and contact alloys engineered to endure extreme cold startup and high internal ambient heat without plastic deformation or contact plating degradation.
Overview and Application Notes
Overview: Engineered for reliable SuperSpeed data transmission, this USB 3.0 Type-A receptacle provides a robust 5 Gbps connection suitable for demanding OEM applications. Featuring a right-angle, mid-mount PCB design, it allows engineers to achieve a lower board profile without sacrificing structural integrity. Manufactured directly in our facility, this through-hole connector ensures excellent retention force and is built to withstand up to 5,000 mating cycles. We offer comprehensive OEM/ODM support, including custom plating options and customized packaging to seamlessly integrate with your automated SMT/DIP production lines.
Application Notes:
-
PCB Cutout & Routing: Requires a specific PCB cutout for the mid-mount configuration. Ensure high-speed differential pairs (TX/RX) are routed with 90-ohm differential impedance to prevent signal degradation.
-
Wave Soldering: The high-temperature LCP/PBT housing is compatible with standard wave soldering profiles. Avoid exposing the contact area to excessive flux residue.
-
Mechanical Reinforcement: Utilize the integrated through-hole shell stakes (shield tabs) to maximize physical retention against the PCB, mitigating stress from frequent plug insertions.
-
EMI Shielding: The metal shell should be properly grounded to the PCB chassis ground plane to minimize electromagnetic interference during 5 Gbps data transfer.
