Frequently Asked Questions
Does this 24-pin Type-C connector support Alternate Modes like DisplayPort or Thunderbolt?
Yes. As a fully populated 24-pin receptacle, it physically supports the high-speed differential pairs required for Alternate Modes, including DisplayPort over USB-C and Thunderbolt 3/4, provided your PCB's controller IC is configured for them.
What is the maximum power output this connector can handle?
The physical contacts are rated for up to 5A on the VBUS pins. When paired with a compliant USB PD 3.1 Extended Power Range (EPR) controller, the connector safely supports up to 240W (48V/5A).
What packaging is used for automated SMT assembly?
We supply this connector in standard Tape & Reel (T&R) packaging equipped with a pick-and-place polyimide cap (Mylar) to ensure seamless compatibility with high-speed automated SMT vacuum nozzles.
What is the Minimum Order Quantity (MOQ) for OEM buyers?
Our standard MOQ for Tape & Reel packaging is typically 1,000 pieces per reel. We also support flexible quantities for engineering validation and NPI (New Product Introduction) builds. Please consult our sales engineering team.
Can I request a 3D CAD model for PCB layout design?
Absolutely. We provide comprehensive engineering support, including 2D mechanical drawings and 3D models (STEP/IGES files). Contact us to request the design files for your footprint verification.
Overview and Application Notes
Overview Engineered for next-generation connectivity, the EU24FB3M1137 is a premium 24-pin USB 3.2 Gen2 Type-C receptacle designed for high-speed data transmission up to 10 Gbps. Featuring a robust top-mount Surface Mount Technology (SMT) design with inner shell stakes, this connector delivers exceptional mechanical stability against severe mating forces on the PCB. It is fully equipped to support high-power delivery applications, including USB PD 3.1 EPR capabilities, making it the definitive choice for industrial PCs, consumer electronics, and automotive infotainment systems. As a factory-direct manufacturer, we offer comprehensive OEM customization and rigorous quality control to ensure seamless integration into your automated assembly lines.
Application Notes
-
Reflow Soldering (SMT): The high-temperature LCP insulator is optimized for lead-free IR reflow soldering. Ensure strict adherence to the coplanarity specifications (typically ≤ 0.08mm) during stencil printing to prevent solder bridging across the high-density 24-pin array.
-
Power Delivery Routing: If utilizing the connector for up to 5A VBUS power delivery (PD 3.1 EPR), ensure PCB traces connected to VBUS and GND pins are sufficiently wide and feature adequate thermal vias to dissipate localized heat.
-
EMI/EMC Shielding: The stainless steel shell incorporates inner stakes. For optimal signal integrity at 10 Gbps (SuperSpeed+), solder these stakes directly to the continuous PCB ground plane to minimize electromagnetic radiation and crosstalk.
-
Mechanical Anchoring: While it is a top-mount SMT component, the shell’s grounding tabs provide essential retention force. Do not rely solely on the signal pins for mechanical stability.
