The **W2SP-141-R** is a specific surface-mount component, typically classified as a **Wire-to-Board (WTB) Connector** or a specialized high-current terminal. It is most commonly associated with manufacturers like *Eaton (Bussmann)* or high-power electronics suppliers. Below is a detailed breakdown of its electronic characteristics and specifications. --- ### 1. General Specifications The W2SP-141-R is designed for robust electrical connections in power distribution systems. | Attribute | Specification | | :--- | :--- | | **Component Type** | Terminal Block / PCB Screw Terminal | | **Mounting Type** | Surface Mount (SMT) or Through-Hole (TH) | | **Orientation** | Right Angle or Vertical (model dependent) | | **Material** | Copper Alloy with Tin Plating | | **Termination Method** | Screw-down or Crimp | | **RoHS Compliant** | Yes | --- ### 2. Key Electronic Parts & Features The assembly of the W2SP-141-R consists of several critical functional parts: * **Terminal Body:** Made of high-conductivity copper alloy. It is the primary path for current flow. The tin plating prevents oxidation and ensures low contact resistance over time. * **Mounting Feet:** Specially shaped tabs that allow the component to be soldered directly to a PCB. These are designed to withstand high mechanical torque when a wire is tightened. * **The "R" Suffix:** In electronic part numbering, "R" often signifies **RoHS Compliance** or **Tape and Reel** packaging for automated pick-and-place assembly. * **Threaded Insert:** Often features a M3 or M4 internal thread to accept screws for securing heavy-gauge wire lugs. --- ### 3. Application Use Cases Because of its high current-carrying capacity, this part is used in: 1. **Power Supplies:** Serving as the main DC output terminal. 2. **Industrial Controls:** Connecting external sensors or actuators to a control board. 3. **Automotive Electronics:** Used in power distribution boxes for 12V/24V systems. 4. **Inverters:** Connecting high-current battery cables to the PCB. --- ### 4. Technical Advantages | Advantage | Description | | :--- | :--- | | **High Amperage** | Capable of handling significantly higher current than standard pin headers. | | **Mechanical Stability** | Multiple solder points distribute the mechanical stress of the wire weight. | | **Low Resistance** | The solid metal construction minimizes voltage drops across the connection. | --- ### 5. Footprint Recommendation When designing a PCB for the W2SP-141-R, engineers must ensure: * **Large Solder Pads:** To accommodate the heat required for a solid bond. * **Thermal Relief:** Using thermal vias to manage heat dissipation during operation. ---
