The **U-R9Z1-R** is a specific part number typically associated with **USB Type-C Connectors**. Specifically, it refers to a high-performance, SMT (Surface Mount Technology) Receptacle used for power delivery and data transfer. Below is a breakdown of its technical specifications, construction, and typical applications. --- ### Technical Specifications | Feature | Description | | :--- | :--- | | **Connector Type** | USB Type-C (Female Receptacle) | | **Mounting Type** | SMT (Surface Mount) + Through-hole Shell Legs | | **USB Standard** | USB 3.1 Gen 2 / USB 4 (Backwards compatible) | | **Current Rating** | Up to 5.0A (Supports Power Delivery) | | **Voltage Rating** | 20V DC | | **Contact Resistance** | 40mΩ Max | | **Operating Temp** | -30°C to +85°C | --- ### Key Construction Features * **Mid-Mount/Hybrid Design:** Many variations of the R9Z1 series feature a "mid-mount" design where the connector sits partially inside a cutout in the PCB. This reduces the total height of the device. * **Durability:** These connectors are rated for approximately **10,000 mating cycles**, making them suitable for consumer electronics that require daily charging. * **Shielding:** The outer shell is typically made of Stainless Steel with Nickel plating to ensure EMI/RFI protection and mechanical strength. * **Pin Configuration:** It utilizes a 24-pin layout (12 top, 12 bottom) to allow for the "reversible" plug feature inherent to Type-C. --- ### Pinout Functional Groups The U-R9Z1-R pins are categorized into four main functions: 1. **Power (VBUS/GND):** Large pins designed to handle high current for fast charging. 2. **Configuration Channels (CC1/CC2):** Used for cable orientation detection and Power Delivery (PD) negotiations. 3. **High-Speed Data (TX/RX):** Differential pairs used for USB 3.1/4.0 speeds. 4. **Legacy Data (D+/D-):** Central pins used for USB 2.0 compatibility. --- ### Common Applications * **Mobile Devices:** Smartphones, tablets, and handheld gaming consoles. * **Charging Ports:** Power banks and wall chargers. * **Laptops:** Slim-profile ultrabooks where vertical space is limited. * **Peripheral Devices:** External SSDs and high-speed docking stations.
