The **SVFH-5W6-R** is a high-performance, high-voltage automotive-grade connector component manufactured by **JST (Japan Solderless Terminals)**. It is part of the **VF Connector series**, specifically designed for heavy-duty applications in Hybrid and Electric Vehicles (HEV/EV). --- ## Technical Specifications Overview | Feature | Specification | | :--- | :--- | | **Manufacturer** | JST (Japan Solderless Terminals) | | **Series** | VF Connector | | **Part Type** | Female Terminal / Receptacle Contact | | **Wire Range** | 3.0mm² to 5.0mm² (Approx. 12 AWG to 10 AWG) | | **Current Rating** | Up to 40A (depending on wire size) | | **Voltage Rating** | 600V AC/DC | | **Plating** | Tin-plated (Reflow treated) | | **Material** | Copper Alloy | --- ## Key Features and Construction ### 1. High Current Capacity The "5W" in the part number indicates its compatibility with larger wire gauges (up to 5mm²). This allows the terminal to handle the high current demands of automotive power systems, such as inverter connections or battery distribution units. ### 2. Vibration Resistance Automotive environments are subject to constant mechanical stress. The SVFH-5W6-R features a **box-shaped contact design** that provides multiple points of contact. This ensures a stable electrical connection even under high-vibration conditions. ### 3. Safety and Locking Mechanism When inserted into the corresponding VF series housing (e.g., VFLP-02V-E), the terminal is secured by a primary and secondary locking system (TPA - Terminal Position Assurance). This prevents "terminal back-out," which is a common cause of electrical failure in high-voltage systems. ### 4. Material Integrity * **Base Material:** Highly conductive copper alloy ensures low contact resistance, reducing heat buildup during high-current flow. * **Plating:** Reflow tin plating helps prevent the formation of "tin whiskers" and provides excellent corrosion resistance. --- ## Applications The SVFH-5W6-R is typically found in the following automotive subsystems: * **On-board Chargers (OBC):** Connecting the power input to the battery management system. * **DC/DC Converters:** Managing power distribution between high-voltage and low-voltage systems. * **Inverter Power Links:** Facilitating power flow to electric motors. * **Battery Junction Boxes:** Main power distribution hubs. ---
