# USB4520-03-0-A (Component) ## Description USB-C (USB TYPE-C) USB 2.0 Receptacle Connector 24 (16+8 Dummy) Position Board Edge, Cutout; Surface Mount; Through Hole, Right Angle The USB4520-03-0-A from Global Connector Technology (GCT) is a mid-mount USB Type-C connector that supports USB 2.0 signaling. It is engineered for space-saving PCB layouts, combining both surface-mount and through-hole (hybrid) mounting for improved mechanical strength and reliability. It features a right-angle, board-edge design, making it suitable for devices where the USB-C port needs to be accessible from the edge of the enclosure. Electrical & Interface USB Type-C receptacle (female) Supports USB 2.0 data transfer 24 total positions (16 active + 8 dummy pins) for mechanical compatibility Reversible plug orientation (standard USB-C feature) Mechanical Design Mid-mount (mid-plane) design → partially recessed into PCB for lower profile Right-angle orientation for edge-mounted applications Hybrid mounting: Surface-mount signal pins Through-hole shell tabs for mechanical reinforcement Designed for board-edge cutout integration Form Factor & Durability Compact footprint for space-constrained designs Robust retention due to through-hole anchor tabs Typically rated for thousands of mating cycles (standard for USB-C connectors) Application Use Cases Embedded systems (e.g., ESP32-based boards) Consumer electronics (chargers, hubs, IoT devices) Industrial control interfaces Portable devices requiring USB-C power/data Design Notes (Important for PCB Layout) Requires PCB cutout for mid-mount placement Pay attention to: Keepout zones under the connector Differential pair routing (D+ / D−) for USB 2.0 Ensure proper mechanical anchoring to avoid stress on SMT pads #commonpartslibrary #connector #usb #typec ## Component Details - **Owner:** adrian95 - **Created:** 12/23/2023 - **Last Updated:** 4/30/2026 - **Visibility:** Public - **Datasheet URL:** https://gct.co/files/specs/usb4520-spec.pdf - **Symbol Style:** parametric-v1 - **Manufacturer Name:** GCT - **Manufacturer Part Number:** USB4520-03-0-A - **Part Type:** Connector - **License:** https://creativecommons.org/licenses/by/4.0/ - **Used in:** 1257 projects - **Forks:** 1 ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
