Frequently Asked Questions
What is the main advantage of the -55°C to +105°C temperature rating?
Commercial USB connectors are typically rated for -20°C to +85°C. Our wide-temperature industrial design uses specialized high-temp thermoplastics and resilient contact alloys, preventing thermal deformation and contact loss under severe temperature fluctuations.
What is the standard Minimum Order Quantity (MOQ) for volume orders?
Standard factory MOQ is typically 1,000 to 5,000 pieces depending on packaging specifications. We also support smaller quantities for engineering prototype runs (EVT/DVT).
Can we order custom gold plating on the contacts for higher durability?
Yes. While standard option is gold flash, we support selective 15µ" or 30µ" gold plating options on the contact area to enhance corrosion resistance and cycle life in harsh chemical or high-humidity environments.
Are CAD models and PCB footprint layout drawings available?
Yes, complete 2D engineering drawings with exact board cutout dimensions and 3D STEP models are provided to support your circuit board layout and enclosure modeling.
Do these connectors comply with international environmental regulations?
All raw materials and electroplating processes fully comply with RoHS 2.0, REACH, and UL94V-0 flammability standards required for EU and North American markets.
Overview and Application Notes
Overview: Engineered for rugged industrial environments and high-speed data transmission, this USB 3.0 Type-A female receptacle delivers reliable 5 Gbps performance for demanding OEM/ODM applications. Featuring a right-angle DIP through-hole mount with a 3.50mm centerline height, it provides superior mechanical shear resistance against heavy cable pulls. Rated for an extended operating temperature range of -55°C to +105°C and tested for up to 10,000 mating cycles, this connector ensures long-term contact reliability in harsh field conditions. Direct factory supply allows flexible customization including selective gold plating thicknesses and custom tray packaging for automated DIP lines.
Application Notes:
-
Extreme Thermal Endurance: Certified for operating environments from -55°C to +105°C, making it ideal for unconditioned outdoor cabinets and high-temperature industrial control units.
-
High-Speed Differential Routing: Route the SuperSpeed differential signal pairs (TX+/TX-, RX+/RX-) with strict 90-ohm differential impedance and minimal via transitions to prevent signal attenuation.
-
PCB Retention & Grounding: Ensure inner shell stakes (shield tabs) are thoroughly soldered into the PCB grounding plane to withstand insertion forces up to 3.57 kg and provide maximum EMI shielding.
-
Soldering Process: High-temperature thermoplastic housing complies with standard lead-free wave soldering profiles without plastic deformation or contact misalignment.
