Frequently Asked Questions
Is this receptacle fully compliant with the new 240W USB PD 3.1 standard?
Yes. The contacts are engineered for a 5A continuous current on the VBUS pins and can handle up to 48V DC, making it fully capable of supporting the 240W Extended Power Range (EPR) specification safely.
What is the standard MOQ and lead time?
Our standard Minimum Order Quantity (MOQ) for tape-and-reel packaging is typically 1,000 pieces per reel to support automated SMT assembly. Lead times generally range from 2 to 4 weeks, depending on current factory capacity.
Can this connector withstand lead-free reflow soldering processes?
Absolutely. The housing is molded from high-temperature Liquid Crystal Polymer (LCP) rated at UL94V-0, making it fully compatible with standard RoHS lead-free IR reflow soldering profiles up to 260°C.
Do you provide 3D CAD models and PCB footprints?
Yes, we provide comprehensive technical documentation. 2D dimension drawings, 3D STEP files, and recommended mid-mount PCB cutout guidelines are available upon request to assist your hardware engineers.
Are the shell stakes also Surface Mount (SMT)?
Yes, this specific part number (18.EU24F2B3N11385SR) features full SMT termination for both the 24 signal contacts and the outer shell stakes, streamlining your assembly process to a single reflow pass.
Overview and Application Notes
Overview: The USB 3.2 Gen2 Type-C Mid-Mount Receptacle is engineered for high-bandwidth data transmission (up to 10 Gbps) and next-generation power delivery. Featuring a space-saving mid-mount (sink board) design, it significantly reduces the Z-axis height on the PCB, making it ideal for ultra-thin profile applications. This 24-pin connector utilizes precision Surface Mount Technology (SMT) for both contacts and shell stakes, ensuring excellent signal integrity. Fully rated for 240W (48V/5A) Extended Power Range (EPR), it offers exceptional industrial-grade durability with a 10,000-cycle lifespan. As a factory-direct OEM/ODM manufacturer, EDOM Electronics ensures strict quality control and reliable volume production for your assembly lines.
Application Notes:
-
PCB Cutout & Routing: Requires a precise PCB cutout for the mid-mount installation. Maintain 90-ohm differential impedance for the SuperSpeed TX/RX traces to guarantee full 10 Gbps bandwidth.
-
Thermal & Power Management: When operating at the maximum 240W (48V/5A) EPR rating, ensure substantial copper pour on the PCB VBUS and GND planes to facilitate adequate thermal dissipation.
-
Reflow Soldering: The high-temperature LCP housing is fully compatible with standard RoHS lead-free IR reflow soldering profiles. Ensure the solder paste formulation matches the fine-pitch SMT requirements.
-
EMI/RFI Shielding: Properly ground the stainless steel outer shell to the PCB ground plane via the SMT stakes to minimize electromagnetic interference in high-frequency data environments.
