The part number **KUSBVLPXHT** refers to a specific series of high-performance Universal Serial Bus (USB) connectors manufactured by **Kycon**. This component is a specialized USB Type-A socket designed for surface mount applications where durability and high-temperature resistance are required. Below is a detailed breakdown of its electronic and mechanical specifications. --- ### 1. Key Technical Specifications | Feature | Specification | | :--- | :--- | | **Connector Type** | USB Type-A (2.0) | | **Gender** | Receptacle (Female) | | **Mounting Type** | Surface Mount (SMT) / Vertical Orientation | | **Voltage Rating** | 30V AC/DC | | **Current Rating** | 1.0A per contact | | **Contact Plating** | Gold Flash (Standard) or 30µ" Gold | | **Housing Material** | High-Temperature Thermoplastic (UL94V-0) | | **Operating Temperature** | -55°C to +85°C | --- ### 2. Breakdown of the Part Number Kycon uses a specific coding system to define the attributes of this connector: * **KUSB**: Indicates the Kycon USB series. * **VLP**: Stands for **V**ertical **L**ow **P**rofile. This means the connector stands upright on the PCB rather than lying flat, saving horizontal board space. * **X**: Often denotes a specific variation in shielding or pin length (refer to datasheet for specific revision). * **HT**: Stands for **H**igh **T**emperature. This indicates the insulator material is designed to withstand **reflow soldering** temperatures (typically up to 260°C). --- ### 3. Electronic Features & Advantages #### A. Vertical Orientation Unlike standard horizontal USB ports found on the side of a laptop, the "V" in this part signifies a vertical orientation. This is ideal for: * Embedded systems where the USB port faces "up" through an enclosure. * Densely packed PCBs where "footprint" space is more valuable than height. #### B. High-Temperature Compatibility The **HT** designation is critical for modern manufacturing. Standard plastic connectors melt during lead-free reflow soldering processes. The KUSBVLPXHT uses LCP (Liquid Crystal Polymer) or high-temp nylon, allowing it to pass through automated soldering ovens without deformation. #### C. Shielding and Grounding The connector features a full metal shield (usually copper alloy with nickel plating). This provides: * **EMI/RFI Protection:** Prevents electromagnetic interference from affecting the data signals. * **Mechanical Integrity:** The shield usually includes "tabs" or "kinks" that are soldered to the board to provide structural support so the connector doesn't snap off during cable insertion/removal. --- ### 4. Common Applications * **Industrial Control Panels:** Where space is tight and ports must face outward from the board surface. * **Charging Stations:** Vertical ports allow for "top-down" docking. * **Data Loggers:** Used in compact devices to download stored information. * **Automotive Electronics:** Due to the high-temperature rating and robust construction.
