The **SVF-0B-R** is an electronic component manufactured by **JST (Japan Solderless Terminals)**. It is a female crimp terminal belonging to the **SVF series**, specifically designed for automotive and high-reliability wire-to-wire or wire-to-board applications. --- ### 1. Key Technical Specifications Below are the primary physical and electrical characteristics of the SVF-0B-R terminal: | Property | Specification | | :--- | :--- | | **Manufacturer** | JST (Japan Solderless Terminals) | | **Type** | Crimp Terminal (Female/Receptacle) | | **Applicable Wire Size** | 0.3 mm² to 0.5 mm² (Approx. 22-20 AWG) | | **Material** | Copper Alloy (High Conductivity) | | **Surface Finish** | Pre-tinned (Reflow tin-plated) | | **Current Rating** | Depends on housing (Typically up to 7A - 10A) | | **Insulation Diameter** | 1.4 mm to 1.9 mm | --- ### 2. Physical Construction and Design The terminal is engineered for durability in environments where vibration and thermal cycling are common. * **Box Contact Design:** The "B" in the part number often refers to the box-style construction of the receptacle, which protects the contact points and ensures a stable connection with the male pin. * **Lance Locking:** These terminals feature a locking lance mechanism that clicks into the connector housing to prevent "terminal back-out" (where the wire pulls out of the plastic shell). * **Material Strength:** Made from a copper alloy, it provides a balance between high electrical conductivity and the mechanical spring force required to maintain contact pressure over time. --- ### 3. Part Number Breakdown Understanding the suffix and prefix helps in identifying the exact variant: * **SVF:** Series designation (often used in JST's automotive/specialty connectors). * **0B:** Indicates the size/type of the terminal and its compatibility with specific wire gauges. * **R:** Usually denotes the packaging type, where **R** stands for **Reel** (intended for use with automated crimping machines or applicators). --- ### 4. Typical Applications The SVF-0B-R is most commonly found in: 1. **Automotive Electronics:** Internal wiring for sensors, lighting, and control modules. 2. **Industrial Equipment:** High-vibration machinery interfaces. 3. **Consumer Appliances:** Internal power distribution where reliable crimp connections are required. ---
